Health and character documents can take time to organise, especially if you need certificates from overseas, translations, or extra medical follow-up. The goal is to prepare early enough that you do not delay your application, but not so early that a certificate expires before Immigration New Zealand (INZ) can use it. This page gives general timing guidance only — requirements can change, and your visa pathway may have specific rules.
What this means for you
For many New Zealand visa applications, INZ needs to assess whether you meet health and character requirements. This may involve an immigration medical exam, chest x-ray, blood tests, and police certificates from countries where you have lived for a required period.
The timing matters because these documents usually have a validity period. If a medical or police certificate is too old when you apply — or when INZ asks for it — you may need to repeat the process. That can mean extra cost, delays, and stress.
As a general approach, do not treat medical and police certificates as “the first thing to do” unless INZ or a licensed adviser has confirmed that it is the right time. If you are still unsure which visa pathway fits you, start with a broader check of your options through the [free eligibility checker](/eligibility-checker/) before booking appointments or requesting overseas certificates.
How it works step by step
A sensible order is usually:
1. **Identify your likely visa pathway.** Different visas can have different document requirements. A work visa, partner visa, student visa, or residence pathway may not ask for the same evidence at the same time. 2. **Check whether INZ already has recent health information.** If you have completed an immigration medical exam before, INZ may be able to reuse it in some situations, depending on timing and the type of application. 3. **Confirm which countries need police certificates.** This depends on where you have lived and for how long, and the rules can vary by visa category. 4. **Plan for the slowest document first.** Some police certificates are quick; others can take weeks or longer, especially if you need documents from overseas. 5. **Book medicals close enough to application time.** Medical results are usually submitted electronically by panel physicians, but timing still matters. 6. **Allow time for translation, certification, and upload.** If a document is not in English, INZ generally requires an acceptable translation.
For more detail on the medical side, see our guide to the [New Zealand immigration medical exam](/immigration-medical-exam-nz/). If you are dealing with Chinese police clearance documents, our guide to getting a [police certificate from China](/police-certificate-from-china/) explains common preparation issues.
What to prepare
Before you spend money on certificates, prepare the basics so you can move quickly when the timing is right:
- **Passport details** for you and any family members included in the application. - **Your travel and residence history**, including countries where you have lived, worked, studied, or stayed for longer periods. - **Previous INZ medical references**, if you have completed immigration medicals before. - **Any known health history**, medications, or specialist reports that may be relevant. - **Names used in the past**, including previous names, Chinese characters, aliases, or different passport spellings. - **Translation and certification plans** for any non-English documents.
It is also useful to understand the bigger picture: INZ is assessing whether you meet New Zealand’s [health and character requirements](/health-and-character-requirements/), not simply whether you can collect paperwork. If there is a medical condition, a past conviction, an old visa issue, or a complicated travel history, it is better to get licensed advice before lodging.
Mistakes to avoid
The most common mistake is ordering every certificate too early. This can happen when people are eager to be “fully prepared”, but immigration documents are time-sensitive. If your application is delayed — for example, because you are still waiting for a job offer, relationship evidence, English results, occupational registration, or an Expression of Interest outcome — your certificates may become less useful.
Another mistake is assuming that one certificate covers every application. A document that worked for a previous visa may not be accepted for a later visa if it is too old, does not cover the right period, or was issued by the wrong authority. Always check current INZ instructions for your visa type.
Also avoid booking a medical with a doctor who is not an approved panel physician where one is required. INZ immigration medicals generally need to be completed through approved systems, not just any local GP. For police certificates, avoid unofficial translations or unclear scans, because document quality issues can slow down assessment.
Finally, do not ignore potential problems and hope they will disappear. If you have a health condition, past visa refusal, police record, drink-driving conviction, or missing overseas document, a licensed adviser can help you understand the correct process before you lodge.
Where to go next
If you are early in your New Zealand immigration journey, your next step is usually to confirm the visa pathway first, then plan documents around that pathway. For example, someone applying for an Accredited Employer Work Visa may have different timing pressures from someone preparing a partner visa or residence application.
If you already know your pathway, make a simple document timeline: likely lodgement date, expected certificate processing times, translation time, and any medical appointment availability. Build in a buffer, but keep expiry risk in mind.

What we can do is help you understand the process, organise your questions, and connect you with an IAA-licensed immigration adviser or immigration lawyer for case-specific guidance.
This is especially important if your certificates are difficult to obtain, your health or character history is not straightforward, or your application timing is tight. A licensed adviser can confirm which documents are needed, when to request them, and how to reduce avoidable delays.
You can start with the [free eligibility checker](/eligibility-checker/) or [book a free intro call](/contact/) to be matched with a licensed adviser. Always confirm current requirements with INZ or a licensed adviser before relying on timing decisions for a real application.
