To create a Simplicity KiwiSaver account for your child please complete the online application form here. You'll need your child's birth certificate and IRD number, and identification and an IRD number for at least one of the child's parents or guardians.

If you’re already a member of Simplicity, you can use the same email address you provided when you signed up. This allows you to view the accounts under one login or you can enter your child's email address if you prefer them to have online access to view their Simplicity account.

If your child is 16 or 17 years old, and meets the other eligibility requirements, they are entitled to the government contribution. 

From 1 April 2026, 16 and 17 year olds who are working and contributing will also qualify for employer contributions.
