The NZDF interview is the stage where the Defence Force stops looking at your test scores and starts looking at you. Defence Careers places it after the earlier assessment stages, and a successful interview leads either into the candidate pool or, for selected trades, to a selection board. That makes it one of the few points in the joining process where the way you talk about yourself directly changes the outcome.
This guide covers what the interview is designed to assess, the four current NZDF values in plain interview language, how to turn each one into a personal example, and how to answer the two questions that come up in almost every account of the process: why the NZDF, and why this trade.

What the NZDF interview actually assesses
The available descriptions of the NZDF interview characterise it as behavioural, with clear attention to how well the candidate understands the organisation’s values. In practice that means you are asked about things you have already done, not about what you think you would do in a hypothetical scenario.
The NZDF describes its values as guiding actions both on and off duty. That single point should shape how you answer. A definition of courage or comradeship, recited neatly, tells the interviewer nothing about you. A short, specific account of a time you spoke up or backed a teammate tells them a lot.
Preparation material also identifies knowledge of your chosen trade as something to be ready to discuss. So there are two broad assessment strands: evidence of the values in your own behaviour, and evidence that you have actually looked into the work you are applying for.
One more thing worth saying plainly: no official NZDF or Defence Careers source publishes a fixed list of interview questions. Anything you see online presented as “the NZDF interview questions” is a preparation theme, not a script. Prepare the themes and stay flexible with the wording.
Who conducts the interview and what the format means
The official Defence Careers application page describes it simply as an interview with one of the NZDF team. Preparation sources describe the behavioural interview at A-Day as being conducted by a Recruiting Officer. Either way, expect a conversation rather than an interrogation.
Treat it as an evidence conversation. For each question, aim to cover what you did, how you worked with other people, and what you took away from it. NZDF leadership doctrine describes leadership as influencing, motivating and enabling others ethically, and notes that leadership can be exercised by anyone regardless of position. That is useful framing for answers about teamwork: you do not need to have held a formal title to show you influenced an outcome.
The NZDF purpose and ethos behind a credible answer
Before you rehearse examples, get clear on what the organisation actually does. The NZDF states its purpose as advancing New Zealand’s interests through military operations and preparation across the sea, land, air, space and information domains, alongside humanitarian work, disaster relief and peacekeeping. The NZDF is made up of 15,305 regular force personnel, reserves and civilian employees.
The word ethos carries weight here. The New Zealand Army ethos is serving New Zealand loyally and honourably, built on two elements: loyalty, reflected in the oath of allegiance to the Crown and the New Zealand Government, and honour, reflected in a high standard of behaviour that protects the Army’s reputation and respects its military heritage. If you are applying to the Army, that ethos is worth understanding, because it explains why behaviour off duty matters as much as performance on task.
Official NZDF career material frames a Defence career around a sense of purpose and the honour of representing New Zealand. Defence Careers describes the Army as a tight-knit team, at the frontline of the country’s defence, working alongside the Navy and Air Force as well as other government and non-government agencies. That language is a hint about what a good motivation answer sounds like: service and contribution first, personal benefit second.
The four current NZDF values in interview language
The current official NZDF position lists four core values. You will occasionally see an older doctrine formulation naming only three, so be aware of the difference, but for interview preparation use the four published on the NZDF’s purpose and values page and repeated across current Defence material.
Tū Kaha, Courage. Moral and physical strength to do what is right. That includes speaking up about unfairness, admitting mistakes and learning from them. Physical courage is overcoming fear in the face of danger; moral courage is making difficult decisions and standing by your principles under pressure.
Tū Tika, Commitment. Doing your best, finding a way to complete the task, and persevering through challenges, while respecting your colleagues and the people of New Zealand. Army material adds the idea of working as one team and putting others before self when necessary.
Tū Tira, Comradeship. Respect, fairness, inclusion and working as a cohesive team, while rejecting harmful behaviour. It means looking after each other and recognising that a team achieves more than individuals working alone.
Tū Maia, Integrity. Acting honestly and ethically to professional standards, fulfilling promises, accepting responsibility, and doing the right thing when nobody is watching. Honesty, sincerity, reliability and consistency.
W/O Kerry Williams, Warrant Officer of the Air Force, put the four values in blunt terms in an NZDF piece on living the values:
My message to recruits is three things – step out of bed every morning and be a good human; every now and then be an even better human; and look after your mates. If they do those three things standing on our foundation of values, they can’t fall far.
He described integrity as doing what you said you would do, and translated it into Air Force life as the actions people take when nobody is looking: leading by example, doing the right thing, and calling on comradeship. He also described commitment as making personal sacrifices and committing to your mates and your role in the service, and courage as what it takes to demonstrate that commitment and integrity when supporting people in challenging and unfamiliar environments.
Turn each value into a personal example
The most common preparation mistake is learning the four value definitions and stopping there. The NZDF’s own framing is that values are lived through actions, so your job in the interview is to supply the actions.
Pick one real situation per value. Work, sport, study, family, volunteering and part-time jobs all count. What matters is that the story is yours, that you can describe it in a couple of minutes, and that your own contribution is visible in it.
For Tū Kaha, a workable example involves speaking up about something unfair, making a decision you knew would be unpopular, or admitting an error and fixing it. The admission of a mistake is often the stronger version, because it also demonstrates integrity.
For Tū Tika, show sustained effort over time. Perseverance through a difficult training block, finishing a task nobody else wanted, or putting a team responsibility ahead of your own convenience when that was genuinely required.
For Tū Tira, show what you did for other people. Listening to someone who was struggling, including a person being left out, or reorganising work so the team hit the deadline together. Say what the effect was on the group.
For Tū Maia, choose a moment when you were unobserved and did the job properly anyway. Reporting an error in your own work, refusing to cut a corner, or keeping a commitment when it would have been easy to drop it.
A simple structure keeps these answers tight: the situation, the action you took, the effect on the task or the people involved, and the lesson you carry forward. Do not force all four values into every answer. Have one strong example per value and let the interviewer choose which one they want.

Motivation and trade choice: answer the why and the fit
“Why do you want to work at the New Zealand Defence Force?” is a documented question in interview preparation material, and it is where generic answers do the most damage. A response built on the NZDF being a good employer with development opportunities is technically fine and completely forgettable.
Build it in three layers instead. Start with what the NZDF exists to do, in your own words: advancing New Zealand’s interests, and the humanitarian, disaster relief and peacekeeping work that goes with it. Then say what contribution you want to make to that. Finish with the qualities or skills you want to develop through service.
Trade choice needs the same discipline. The three branches offer different lifestyles and different trades, so you should be able to explain why your preferred service fits your interests and longer-term goals. The Navy suits people drawn to maritime security, engineering at sea and electronic warfare, with roles such as Marine Technician, Diver, Electronic Technician and Communications Specialist. The Army is the land-based force focused on disaster relief, peacekeeping and combat, with roles including Infantry Soldier, Combat Engineer, Medic, Logistics Specialist and Intelligence Operator. The Air Force supports air power and logistics across the Pacific, with roles such as Aircraft Technician, Flight Steward, Security Forces and Aircrew.
Show that you know what the day-to-day work of your trade involves, and connect it to something concrete about yourself: the subjects you are good at, the hands-on work you enjoy, the kind of team you want to be part of. The NZDF also presents every role as contributing to the shared mission, so you do not need to claim your trade is the most important one. You need to explain why it is the right one for you.
Where the interview sits in the wider joining process
Understanding the sequence helps you show up to the interview at the right level of preparation. The application process runs through an aptitude test, medical and fitness assessment, the interview itself, and then either the candidate pool or a selection board for certain trades. Some of this is grouped into an Assessment Day, often referred to as A-Day, where the aptitude test, the Initial Fitness Test and the behavioural interview can fall on the same visit.
Fitness testing sits alongside the interview rather than inside it, but candidates commonly prepare for both at once. The Beep Test, also called the MSFT, features in entry testing, and Defence Careers publishes Force Fit material to help applicants prepare. Detailed pass marks are not published by official Defence Careers sources; the figures below circulate through third-party coaching material and should be treated as an indicative training target rather than a confirmed standard.
Note: Army curl-ups were officially removed from entry testing in July 2024.
| Service | Beep Test (MSFT) | Push-ups (Male/Female) | Other |
|---|---|---|---|
| Navy | 6.1 (Updated 2024) | 15 / 10 | Survival Swim |
| Army | 7.5 | 30 / 15 | Curl-ups removed |
| Air Force | 6.5 | 30 / 16 | 5km Weighted March |
Beyond the interview come the later stages: a security clearance process, an Offer of Service, and then Induction Day and attestation before training begins. The Offer of Service, sometimes shortened to OOS, is the formal offer that follows a successful application. Army recruits complete their Recruit Course at Waiouru, Navy initial training takes place at Devonport Naval Base, and officer candidates go through Officer Cadet School. A commercial coaching site states there is a lifetime limit of three attempts at the aptitude tests, with stand-down periods of three months after a first failure and twelve months after a second; no official NZDF source publishes attempt limits, so confirm this directly with your Recruiter rather than planning around it.
Knowing the sequence also gives you something useful to say in the interview. It shows you have looked into the commitment properly rather than just liking the idea of a uniform.
What weakens or can end an interview answer
The official process page does not publish a failure checklist. It sets out what happens when the interview goes well. So the risks below are drawn from the values themselves rather than from any official marking scheme.
Claiming a value you cannot evidence is the fastest way to lose credibility. If you say you have integrity and then cannot describe a single occasion when it cost you something, the claim is empty. The same applies to courage described only in the abstract.
Avoiding responsibility for a mistake is a serious problem in this context, because the NZDF explicitly links courage with learning from mistakes rather than hiding them, and integrity with accepting responsibility. An answer that blames a manager, a teammate or bad luck for everything reads as a warning sign.
Dismissing teamwork sits badly against Tū Tira. Comradeship includes fair treatment, inclusion and respect, and the NZDF values framework rejects racism, sexism, homophobia, xenophobia and other harmful behaviour. W/O Williams also pointed to the need to consider the impact of individual behaviour and the willingness to call out conduct when necessary. An answer that treats respect as optional runs directly against that.
Finally, avoid dishonesty of any kind about your history, experience or fitness. The later stages of the process, including the security clearance, are not the place for a story to fall apart.
A final rehearsal checklist
Prepare one genuine example for each of the four values and rehearse them out loud, not just in your head. Aim for two minutes each, with the action and the outcome clearly stated.
Keep every story personal and specific. Names of tasks, rough timeframes and what actually changed are what make an example believable. Broad claims about being a hard worker are not.
Connect at least two of your examples to a team result. The NZDF treats inclusion as fundamental to working together as one for the good of New Zealand and links its values directly to strengthening teams. The NZDF also describes culture as shared behaviour, meaning what you encourage or discourage becomes part of the organisation’s culture. That is a good reason to show, in your examples, that you already think about your effect on other people.
Then finish each answer with the lesson you carry forward. As the NZDF puts it, aligning your personal values with the Defence Force’s contributes to a strong team and better outputs. Your next concrete step: write out four short examples this week, one per value, then read them back and cut anything that does not describe something you personally did.
Frequently Asked Questions
What questions will I be asked at an NZDF interview?
There is no fixed official question list. Prepare for behavioural prompts about the four NZDF values, your chosen trade, and why you want to serve. Treat examples you find on preparation websites as practice themes, not guaranteed NZDF wording.
What are the five hardest interview questions for NZDF applicants?
The NZDF does not rank its questions by difficulty. The most demanding preparation areas are likely to be why the NZDF, why your chosen trade, a Courage example, a Comradeship example, and an Integrity or mistake example. These are inferred from the published values and the available descriptions of the interview, not official questions.
What are the five main questions asked at an NZDF interview?
No standard set of five questions is published. Build your answers around motivation, trade knowledge, personal evidence of the values, teamwork and responsibility for mistakes. Practise these as themes rather than treating them as a script.
What are the core values of the New Zealand Defence Force?
The current official NZDF values are Tū Kaha, Courage; Tū Tika, Commitment; Tū Tira, Comradeship; and Tū Maia, Integrity. They are intended to guide behaviour both on and off duty, including how people work together and take responsibility.
Does the NZDF have three, four, five or seven core values?
Use four for current interview preparation: Tū Kaha, Tū Tika, Tū Tira and Tū Maia. An older NZDF doctrine publication presents three values, but the current official NZDF website and other current sources use four. There is no supported five or seven value NZDF list.
How should I answer a values-based NZDF interview question?
Use a real situation and explain the action you took, the effect on other people or the task, and what you learned. Link the story to one value, such as speaking up for Courage, supporting the team for Comradeship, or taking responsibility for Integrity. Do not simply recite the value definition.
How do I answer “Why do you want to join the NZDF?”
Anchor the answer in the NZDF’s purpose of advancing New Zealand’s interests and supporting people through its military and humanitarian work. Then add the contribution you want to make and the skills or qualities you want to develop. A generic claim that the NZDF is a good employer is much weaker than a specific, informed reason for service.
How should I explain my choice of trade?
Show that you understand what the trade does and why its work suits your interests, strengths and longer-term goals. Connect the trade to the service you want to join and the contribution you hope to make. Interview preparation material specifically identifies knowledge of the chosen trade as something to prepare for.
What can make an NZDF interview answer unsuccessful?
The official material does not publish a failure checklist. Answers are likely to be weakened by unsupported claims, dishonesty, avoiding responsibility for mistakes, dismissing teamwork or showing disrespect towards others. These are preparation warnings based on the NZDF values, not an official marking scheme.
