Kiwis will know tomorrow which flags they can vote for in the first referendum that will help decide if New Zealand adopts a fresh design.
The Flag Consideration Panel will name the four alternatives tomorrow at 10am from Te Papa in Wellington, which will then be subjected to the first referendum later this year.
Prime Minister John Key said the "four were a good reflection on what was over 10,000 designs, distilled down to 40".
"I think there’s two or three there that could be a new New Zealand flag. It will be for New Zealanders to decide.
"My sense is that there’s quite a bit of movement happening. People who initially thought they would stay with the old flag are now starting to think they’ll move over and go with a new one."
Mr Key reiterated his preference for a silver fern flag.
"The story of New Zealand is based around that. It’s been used in all sorts of way by New Zealanders for a very long time. In my mind a flag that’s going to be successful is one that’s instantly recognisible."
The $26 million campaign allowing Kiwis to decide if they want a new flag, and if so which one, has been met with feverous debate.
Voters will decide which flag from the four choices will go head-to-head with the current New Zealand flag in a second referendum next March.
Both referendums are binding. No date has yet been set for the first referendum, which is expected to take place in November or December.
