Nikki Kaye entered Parliament in 2008 as the National Party's first-ever Auckland Central MP, claiming an electorate which had been held by left-leaning parties for 90 years.
She held onto the electorate by very narrow margins against another rising star, Labour's Jacinda Ardern, in 2011 and 2014.
Kaye became a government minister in 2013, taking on the Food Safety, Civil Defence and Youth Affairs portfolios, and associate education and immigration roles.
After re-election in 2014, she was given greater responsibility, taking on the ACC portfolio.
She is part of National's socially liberal wing. She worked on a cross-party group to legalise same-sex marriage in 2013, and led a campaign within her party to keep the alcohol purchase age at 18 years old in 2012.
