While National Party voters backed their candidate Todd McClay to retain the Rotorua MP seat, he also had the support from voters of the ACT New Zealand Party, United Future, Conservative and Ban 1080 Party.
Figures of split votes for the region from last month's general election have been released by the Electoral Commission.
They show the number of those choosing a different affiliated electoral candidate from their party vote.
There were 34,000 party votes counted in the Rotorua electorate, with 17,660 (52 per cent) going to National.
When it came to the candidate vote, National's Mr McClay won the support of nearly 90 per cent of National voters. But he also enjoyed the backing of 52 per cent (74 votes) of ACT New Zealand voters, 46 per cent (47 votes) from Ban 1080 and 61 per cent (44 votes) of Conservative voters.
