Prime Minister John Key says losing Northland in yesterday's byelection was disappointing but he was "pretty philosophical" about it.
It was effectively a two-candidate contest between National's Mark Osborne and New Zealand First leader Winston Peters who won with a 4012 majority and that could not be translated to a general election.
"Once you back to a normalized scenario where there are a great many more candidates, then the dynamics change dramatically because obviously you get vote splitting and we are by far the biggest party and our candidate will come through," he said today from Melbourne, before the cricket final.
Mr Key said he would take the loss on board.
"The voters are never wrong like, frankly, in my view, the polls are very infrequently wrong.
