Another National MP has announced they will step down from politics before the 2020 election.
National MP for Wairarapa Alastair Scott said in a statement it has been a "privilege" to serve his electorate, and he is confident National will win the next election.
"I'm confident that I leave my seat in good shape for the 2020 election. I am announcing today because it is very important to me that we have sufficient time to find and support our new National Wairarapa candidate for the 2020 election," he said on Tuesday.
"I am grateful to the National Party for the opportunities and support it has shown me over the past six years. The party is full of dedicated individuals who are committed to working hard for New Zealand. I will extend my full support to the newly selected candidate."
His resignation came less than an hour after National MP for Selwyn and member of caucus Amy Adams announced she will also retire at the election.
"I have been incredibly privileged to serve as the MP for Selwyn and a member of the National Party caucus for almost 12 years," she said in a statement on Tuesday.
"Making the decision to step away from politics has not been an easy one but it is the right time for me and my family and I'm looking forward to whatever the future holds."
Adams said she had "every confidence" in the National Party under Simon Bridges' leadership and its prospects for the 2020 election.
