Human Assisted Reproductive Technology Act Statistics

The Human Assisted Reproductive Technology (HART) Register is a record of people conceived from sperm or egg donations made at a New Zealand fertility clinic, and their donors.

The HART Register can help donor-conceived people to:

• learn about their genetic origins
• get in contact with their donor or donors, if all parties agree.

Donors can ask for the names of any children born from their donation, but the child must be 18 or over and give permission.

There are 2 types of records:

• Mandatory registrations — for any donations made at a fertility clinic on or after 22 August 2005 that result in a birth.
• Voluntary registrations — for donations made before 22 August 2005 that result in a birth.

More information about the Human Assisted Reproductive Technology (HART) Register is available on the Govt.nz website.

• Figures include registrations still in progress.
• More registrations for donor conceived people born in 2021 are expected, as fertility clinics follow-up with parents to get information about their child’s birth and complete the paperwork.
• All figures have been manually collated, and as such, small variation to alternate publications may be present
