Prime Minister John Key says he has no intention of pulling out of the job early if his National Party wins a fourth term.
But he's stopped short of being definitive and is keen to point out the party has to actually win it first.
Asked on The Nation whether there could be a situation where National could win the election only for Mr Key to pull out afterwards, he replied: "Well, that's not my intention".
"But, the first point I've got to make is you've got to win a fourth term," he said.
The National Party has only had one four-term Prime Minister: Keith Holyoake whose time ran from 1960 to 1972.
Newshub-Reid Research's August poll had National at 45.1 percent, compared to the Labour Green bloc at 44.2 percent.
