A New Zealand public service interview is usually a structured panel interview with behavioural questions, scored against the skills, experience and thinking the role needs, because agencies must appoint on merit under section 72 of the Public Service Act 2020. Te Kawa Mataaho Public Service Commission's guidance, dated 29 June 2026, recommends structured interviews with standardised questions and rating scales, pre-set criteria and panels that calibrate their scores, so the best preparation is a set of specific, true examples matched to the position description.
This guide explains what that guidance means for you, the public service values and principles panels will expect you to understand, and how a typical process runs from advert to offer. Each agency runs its own recruitment, so always follow the instructions in your invitation. For the wider local picture, see our job interview tips for New Zealand.
How does merit-based selection work in the NZ public service?
Te Kawa Mataaho's guidance on making merit-based employment decisions (dated 29 June 2026, as of October 2026) sets out what agencies should do. The points that shape your interview:
- Merit is defined by the role. Position descriptions and selection criteria should spell out the qualifications, technical skills, sector and stakeholder knowledge, and skills such as critical thinking, emotional intelligence and communication the job needs. Read them line by line, because that's what you'll be scored against.
- Structured interviews. The guidance recommends standardised questions and rating scales, criteria decided in advance, and calibration of assessments across panel members. Expect every candidate to get the same core questions.
- Diverse, bias-aware panels. Panels should bring a range of skills, experience and perspectives, and members should understand common biases, including the risk of mistaking confidence for competence. Substance beats polish.
- Broad experience counts. The guidance says agencies should value cultural capability for working with Māori, skills from the private sector, and paid and unpaid experience, and require qualifications only when they're essential.
- Accommodations. Reasonable accommodations should be available throughout selection, so ask for what you need.
- Checks are stated up front. Agencies should state any required checks or clearances in the job advert.
The guidance notes that it creates no new obligations; it supports agencies to meet the merit requirement in law. Practice still varies between agencies, so treat it as the standard most panels are working towards.
A typical public service recruitment process
Most public service roles are advertised on jobs.govt.nz or an agency's own careers site. Stages differ by agency; the Department of Conservation's published process is a useful real example (as of October 2026).
| Stage | What usually happens | How to prepare |
|---|---|---|
| Advert and position description | Lists the purpose of the role, key accountabilities, required skills and any checks or clearances | Highlight every criterion; it becomes your interview plan |
| Application | CV and cover letter; some agencies add screening questions | Address the criteria directly with evidence |
| Shortlisting | DOC, for example, says it contacts shortlisted applicants within two weeks of the advert closing | Start preparing examples while you wait |
| Pre-interview task (some roles) | A written exercise or presentation; DOC says it gives details in advance | Practise the format and time yourself |
| Panel interview | In person or online; usually behavioural questions scored against the criteria | Prepare 8 to 10 STAR examples |
| Referee checks | DOC says it won't contact referees without confirming with you first | Brief your referees on the role |
| Offer and pre-employment checks | Verbal then written offer; checks such as a criminal convictions history check, and for some roles a security clearance | Have your identity documents ready |
Source for the DOC details: its recruitment process page. DOC says it usually follows a behavioural-based interview format, and that all its staff must complete a Ministry of Justice criminal convictions history check. Other agencies' checks depend on the role.
What values does the NZ public service look for in an interview?
Te Tauākī Whanonga mō te Rāngai Tūmatanui, the Code of Conduct for the Public Sector, took effect on 30 March 2026 and replaced the earlier Standards of Integrity and Conduct. It sets out five values and five principles that public servants must uphold. Panels rarely ask you to recite them, but your examples should show them.
| Value | What the Commission says it means | Practice question (ours) |
|---|---|---|
| Ngākau Pono | Trustworthy | Act with integrity; be open and transparent | "Tell me about a time you admitted a mistake before anyone else noticed it." |
| Whakarangatira | Respectful | Treat all people with dignity and compassion; act with humility | "Describe a time you dealt with someone who was upset or distressed." |
| Ngākau Tapatahi | Impartial | Treat all people fairly, without personal favour or bias | "Tell me about a decision where you had to set aside your own view." |
| Whaiwhakaaro | Accountable | Take responsibility and answer for work, actions and decisions | "Give an example of when you owned a result that didn't go to plan." |
| Āta Whakarongo | Responsive | Understand and meet people's needs and aspirations | "Tell me about a time you changed a service because of feedback." |
The five principles in the Code are political neutrality, free and frank advice, merit-based appointments, open government and stewardship. For policy and advisory roles especially, expect a question about giving advice a manager or minister may not want to hear, or about staying politically neutral.
What questions are asked in a NZ public service interview?
Agencies don't publish their question banks, but structured interviews follow a predictable pattern: an opening question about you and why you want the role, several behavioural questions tied to the position description ("Tell me about a time when…"), sometimes a scenario question ("What would you do if…"), a question about working with Māori or understanding Te Tiriti o Waitangi | the Treaty of Waitangi where the role calls for it, and time for your questions. These practice questions are ones we wrote:
- "Why do you want to work in the public service, and why this agency?"
- "Tell me about a time you had to explain a complex issue to someone without your background."
- "Describe a time you worked with a community, iwi or stakeholder group whose priorities differed from your organisation's."
- "A minister's office asks for advice by tomorrow, and you think the preferred option has a serious risk. What do you do?"
- "Tell me about a time you managed competing deadlines from different managers."
For senior and leadership roles, the public sector's Leadership Success Profile describes what effective leadership looks like, including leading strategically, leading with influence and engaging others; reading it helps you choose leadership examples. If panel formats are new to you, see our guide to panel interviews.
Example answer we wrote: free and frank advice
An example for illustration, not a real candidate's answer. Question: "Tell me about a time you gave advice you knew wouldn't be welcome."
- Situation: "I was an analyst on a regional funding programme. Our manager wanted to announce the first grants before the end of the financial year."
- Task: "Two applications hadn't finished their eligibility checks, and I was responsible for the assessment summary."
- Action: "I wrote a short note setting out the two options: announce all grants on time with a risk that two might be ineligible, or announce the ones that had cleared and the remaining two three weeks later. I recommended the second, explained why, and said I'd support whichever she chose."
- Result: "She chose the staged announcement. One of the two applications turned out to be ineligible, which would have meant withdrawing a public grant. Since then I've written every recommendation with the options and risks laid out the same way."

How to prepare for your public service interview
- Map the position description. List each criterion and write one true example for it, with a measurable result where possible.
- Know the agency. Read its strategic intentions or statement of intent and recent work, and be ready to say how your role contributes.
- Prepare for the values and principles. Have one example each for integrity, impartiality, working with Māori or communities, and advice under pressure.
- Check the pay band. Look for a salary range in the advert or position description, and ask the recruiter if there isn't one. Our guide to answering salary expectations in New Zealand covers how pay conversations work.
- Practise out loud. CoPilot Interview's Mock Interview builds questions from your CV and the position description, reads them aloud, scores each spoken answer out of 10 with what to fix and a model answer, and ends with a report card. The free plan gives you 15 minutes a day with no account, and the browser AI mock interview needs nothing installed. AI feedback can be wrong, so keep your examples in your own words.
