What to Expect from a Paternity Test

Having a paternity test can be stressful and it can be helpful to know what is involved. Here’s what you can expect when you come to DNA Diagnostics for a paternity test. Feel free to contact us before, during and after the DNA test if you have any concerns or queries.


Step 1: Booking a DNA test

Go to the list of laboratory locations and find a collection centre convenient for you. Contact the centre on the number provided.

To arrange an overseas collection contact the main DNA Diagnostics laboratory.

Samples from the alleged father, the mother and the child do not need to be taken at the same time, so each party can come separately if desired.

Step 2: At the DNA sample collection centre

The appointment at the collection centre will take approximately 30 minutes.

Identification requirements

Please bring to the collection appointment for EACH person being tested, including children, the following:

Your identity MUST be confirmed, consent given and the request form completed BEFORE any testing can be undertaken.

The consent reads as follows:

"I agree to provide a sample from myself and/or my child(ren), of whom I am the Legal guardian, to be tested at DNA Diagnostics for the purpose of DNA profiling. I give my permission for the result to be released to the other party directly or through their representative, but agree that no result will be requested until DNA Diagnostics has been paid in full or received a lawyer's guarantee of payment in full."


Testing must be paid in full prior to sample collection, UNLESS alternative arrangements have been made through your lawyer. Payment options are outlined on the Consent and Payment Form.

Please note: if the test does not proceed the case is subject to a cancellation fee of $400.00.


A swab will be placed in your mouth and wiped around the inside of your cheek. Blood can be taken if preferred on request.

Step 3: Performing the DNA test

Samples are then transported to our Auckland laboratory for processing. DNA parentage testing is carried out on site by our highly experienced staff in our ISO 15189 accredited laboratory.

All testing is treated in the strictest confidence. Any information about the paternity test will only be communicated to those tested, or their nominated representative.

Step 4: Getting the results of your paternity test

The results will be released as soon as they are available. The report can be emailed or posted to those tested or their nominated representative. Results WILL NOT be released by phone.

If you have any questions about the result of a paternity test please contact us.
