Former Prime Minister Jim Bolger says it is time to change the New Zealand flag and he hopes New Zealand has "the maturity" to do it and to look forward and not back.
The first of a two-part referendum of the flag begins on Friday and Mr Bolger said he would be voting for the silver fern with the Southern Cross.
The referendum, which runs until December 11, asks voters to rank five alternatives. The most popular one from the preferential voting system will be pitted against the current flag in a second referendum in March.
Mr Bolger made his comments this week while in Vietnam, where dozens of New Zealand flags flew among Vietnamese ones to mark the official visit of Prime Minister John Key to Hanoi.
"I just hope New Zealanders ... look forwards and say, yes we need a new flag looking forward," Mr Bolger said. "I think New Zealand has maturity now to identify ourselves with something that is totally New Zealand-oriented.
