'See ya, mate' - John Key's parting words to Bill English

'See ya, mate' - John Key's parting words to Bill English

"See ya mate, good luck. You're going to be awesome."

Those words from John Key were among the last to his successor-in-waiting Bill English, as he left Parliament as Prime Minister for the last time on Monday.

The pomp and ceremony of the handover of power has taken place, with Mr English elected the new leader unopposed by National's caucus.

Paula Bennett was also elected unopposed as second-in-charge.

Mr Key held his final news conference with journalists on Monday afternoon before leaving from the front steps of Parliament bound for Government House, where he officially resigned.

But before he did, and in front of a large crowd, Mr Key gave his final public words of encouragement for his former Deputy Prime Minister.

Mr English was officially sworn in at Government House on Monday.

As Mr Key got into his Crown car with wife Bronagh, he had one last piece of advice ahead of the official ceremony.

"Enjoy this afternoon."
