THE CONTENDERS

Paula Bennett (48) Bill English’s deputy since last year. Her background as a solo mother stood out in National. Oversaw reform of welfare system. High profile and often underestimated.

Amy Adams (46) Selwyn MP. Former lawyer and justice minister, raised by a solo mum. Credited for National’s work on domestic violence. Supported gay marriage and delivered pardon for those convicted for homosexual acts in the past.

Simon Bridges (40) Raised in Auckland, a former lawyer and Crown prosecutor who beat NZ First leader Winston Peters in the Tauranga seat in 2008. Former economic development and transport minister.

Judith Collins (58) Papakura MP since 2005. Former lawyer dubbed “Crusher” for war on boy racer cars. Fearless. Stood down briefly by John Key after Dirty Politics appeared to link her to efforts to undermine SFO, but inquiry found no evidence. Withdrew from previous leadership election, won by Bill English.

Mark Mitchell (49) The popular former cop and security contractor is MP for Rodney and former defence minister. Married to Peggy Bourne, widow of rally driver Possum Bourne. Likes dogs.

Nikki Kaye (38) Auckland Central MP and former minister. Beat PM Jacinda Ardern twice in Auckland Central. Treated for breast cancer — and a regular at the Coast to Coast. Supports gay rights and environmental protection. Has some public support — but unlikely to stand. This time.

Jonathan Coleman (51) Northcote MP. Former doctor — including for the Flying Doctor Service in Australia. Was defence and health minister in government. Briefly contested leadership when John Key stepped down, but withdrew when English had the numbers.

Steven Joyce (54) List MP and former DJ with an inglorious academic record. Founded the RadioWorks empire. National’s campaign maestro since 2005. Entered Parliament in 2008, appointed to Cabinet straight away. May stand but may also follow English out the door.
