Prime Minister Bill English has revealed he voted for the flag change, but says John Key's failed referendum on this issue showed the perils of politicians rather than people trying to drive change.
It is the first time English has revealed how he voted in the flag referendums. He had refused to give his view at the time because he was in charge of the referendum process.
Now he is Prime Minister, English said the flag referendum showed constitutional changes such as the flag or a move toward a republic should not be led by politicians.
"That is the lesson from the flag referendum. I oversaw the process for changing the flag, I voted for changing the flag. In the end, a lot of the voting became a bit of a political vehicle, probably because it was proposed by the Prime Minister.
"So I think in future that constitutional change needs to come from the will of the people."
