The government has approved the return of 10-year passports for adults.
Internal Affairs Minister Peter Dunne said a law change to lengthen their validity was expected to be place from 31 December 2015.
He said 10-years was more convenient for adult passport holders.
However, because a child’s appearance changes significantly, the child passport would remain at five years.
The price of an adult passport would be no more than $180, including GST – an average saving of more than $90 over the 10-year validity period.
