National's Waimakariri's MP, Matt Doocey, says his party's poor result this election is partially due to a lack of "internal discipline".
"You can go back to Jami-Lee Ross, Hamish Walker, Andrew Falloon, we had a leak just before the election, leadership issues," he told Chris Lynch.
"If you don't looklike you can manage yourself, no one is going to trust you to manage the country.
"Quite rightly Judith Collins, who I 100 per cent support, has said we are going to have to have a review and a bit of a reset."
The National Party scandals included Jami-Lee Ross who stood down after accusing Simon Bridges of corruption, Andrew Falloon who sent porn to a teenager, Hamish Walker who leaked Covid-19 patient details, leadership changes and the leak of an email to caucus from a frustrated Denise Lee.
He said a good Opposition was needed to "hold the Government to account".
People also voted for "continuity", he said, in an election dominated by Covid-19.
Although he held on to his Waimakariri electorate, Doocey's majority last election – 10,766 votes – was wiped away over the weekend, with him keeping his seat with a much slimmer 1976 majority.
