Providing DNA test results

Find out about the optional DNA test process, and how to agree to a test or choose not to have it.

Identity and character

Sometimes we may ask you to get an optional DNA test and send us the results.

Usually, we send a DNA test request when there was no relationship evidence, or we need more. The test is used to confirm a biological relationship for your visa application. 

The test, which is a quick swab of the inside of your mouth, is only accepted when carried out:

  • using standard procedures, and
  • by a DNA sampler working at an Immigration New Zealand (INZ) approved DNA testing laboratory.

How we set up your DNA test

All requests for DNA test results are optional.

Check what to do if you agree to the test or choose not to have it.

We send you a DNA test request letter and declaration

If you decide you:

  • want the DNA test send us your declaration and any required payment before the 'return by date' in the letter
  • do not want the test ignore the request — when your declaration is not with us by the return date we assume you did not want the test. 

Return your declaration with any payment

To have the test, send us your signed declaration and any payment before the 'return by date'.

We make arrangements with a DNA testing laboratory

We let the DNA testing laboratory and their DNA sampler know who they will test and their relationship to you.

You set up your DNA test appointment

  • We let you know the details of the DNA testing laboratory who will do your test.
  • You need to make an appointment with them for the test.

We receive your DNA test results

  • The DNA testing laboratory only posts the results to the INZ branch dealing with your application. 
  • The DNA testing laboratory and INZ cannot give out, or discuss, test results over the phone. Each person tested must ask INZ in writing for a copy of the results.
Alert

Destruction of all test results, samples, paperwork, and electronic files starts from 3 months of receipt. Destruction is completed after 24 months.

Check the DNA testing guide for more information. It includes details about costs, what we do with your test results, and the results destruction process.
