New Zealand allows dual citizenship or multiple citizenship — but some other countries don’t.
Check the other country's rules
You can have NZ citizenship and be a citizen of another country at the same time — unless the other country doesn't allow it. Check with the other country what their rules are.
Dual citizenship if you have a baby in NZ
If you give birth in New Zealand and you or the other parent is an NZ citizen or permanent resident, your baby is automatically an NZ citizen.
If you're from a country that allows dual citizenship, you can also apply to the other country for citizenship for your child.
If you're from a country that doesn't allow dual citizenship, your baby might not be able to give up their New Zealand citizenship to become a citizen of your home country until they turn 18.
If you want your baby to hold citizenship for your home country instead of NZ, you might need to travel home to give birth.
If you have to give up NZ citizenship
You might have to give up your NZ citizenship if you want to become a citizen of a country that doesn’t allow dual citizenship.
