Former Prime Minister Sir John Key believes his successor Bill English delivered a "fantastic election result, "better than I could have".
He thinks the result vindicated his decision to step down nine months ago. "I left on my own terms because I believed we could transition successfully and continue on. So for me success is exactly what happened on Saturday night.
"If Bill had delivered a bad result and the party had lost a lot of MPs people might have looked at me and said that was a selfish step, whereas what happened was, Bill delivered a fantastic result, a better result that I could have. What that shows is we renewed and refreshed and gave ourselves a way, I think, of looking and sounding a little bit different."
Key was overseas for much of the campaign but says he was able to keep in touch - watching the first leaders' debate in his cabin on a cruise ship off Croatia, with Bronagh telling him to stop shouting at the screen. He was also in frequent cellphone contact with English and National's campaign.
He was in New Zealand, though, when Jacinda Ardern was catapulted into the Labour leadership. "I immediately thought she would present the risk she actually did to National because whatever you think of the policies of Jacinda Ardern, she is a very competent and smooth communicator and she had demonstrated that in the time I was in Parliament.
