Labour backs Problem Gambling Foundation manager to win back Christchurch Central.
National's election-year overhaul of MPs and contenders continued over the weekend with the selection of Wayne Walford to contest the battleground Napier seat against former Labour list MP Stuart Nash.
Mr Walford's selection on Saturday to replace departing former minister Chris Tremain follows the selection on Friday of medical practitioner Shane Reti as the replacement for former minister Phil Heatley in the safe Whangarei seat.
Mr Walford, chief executive of the Hawkes Bay Chamber of Commerce, said National had delivered "real results for the Hawkes Bay" and strong local representation in the party had been critical in getting major local projects including roading upgrades "over the line".
"I'll be working hard to win the confidence of the electorate to keep that strong voice and continue delivering jobs and growth for Napier, Wairoa and the Bay."
