Yes! Kernel offers Kids Accounts that can be opened for those aged under 18.
You will need the child’s IRD number, NZ passport or birth certificate and your own NZ passport or drivers license.
You can read how the application process works here.
If the child does not yet have an IRD number and you are their parent or legal guardian you can apply with the IRD online.
If you already have an account with Kernel, you will need to use a different email address when opening a joint account for the child than the one associated with your personal account. You cannot use the same email for both a personal and joint account.
