Ten year passports are due to return by the end of the year, Internal Affairs Minister Peter Dunne has announced.
Mr Dunne said Cabinet had signed off on bringing back a ten year term for adult's passports, making it cheaper and more convenient for travellers.
However, children's passports will remain at five years because a child's appearance changed significantly over time. He said the five year term for children was common in many overseas countries.
The 10-year adult passport price will cost $180, an average saving of more than $90 over the 10-year period.
It will require law changes which he hoped to have in place by the end of the year.
