The MMP system survived the weekend referendum, a sign that tactical voting will remain a part of the political landscape at general elections.
Not everyone votes tactically, however, and as a result some electorates are not as well represented as they might be.
Maori voters in Ikaroa-Rawhiti, for example, could have ensured they had two MPs representing their people had they chosen to vote tactically.
At the ballot box on Saturday voters in Ikaroa-Rawhiti, which includes Hawke's Bay, opted overwhelmingly for Labour's Parekura Horomia, giving him 9523 votes, or 51 per cent of the ballots cast, and ensuring his fifth term in Parliament.
Yet Mr Horomia, at No 6 on Labour's list, was a shoo-in for the next Parliament even without the electorate vote.
