If September's election result reflects current polling, there could be two Napier-based MPs in the next Parliament.
That situation would arise if Labour candidate Stuart Nash wins the seat ahead of National's Wayne Walford, but Mr Walford secures a place in Parliament as a list MP.
Mr Walford is ranked 63rd on National's list, released on Sunday. According to an analysis by right-wing blogger David Farrar, Mr Walford is effectively the 22nd candidate on the list assuming all sitting National MPs were returned, and candidates retain all the seats currently held by retiring National MPs.
That placing would be enough to get him a list seat provided National picked up at least 49.7 per cent of the party vote, according to Mr Farrar's analysis.
National is polling at over 50 per cent in major polls but political observers expect the party's support base to fall back by the time of the September 20 election.
