Had they been of a mind to, Ikaroa-Rawhiti voters could have elected the Maori Party's Na Raihania or Mana's Tawhai McClutchie as their electorate representative and still had the comfort of having Mr Horomia, an MP they obviously trust, in Parliament.
Mr Raihania was the next highest polling candidate with 3599 votes, a good showing for his first national election, but still a long way from threatening Mr Horomia.
It is possible, of course, that Ikaroa-Rawhiti voters largely rejected the Maori Party because of its closeness to the previous National-led Government. Tactical voting will only ever work if voters decide it's a win for them.
That's what the blue-blooded residents of Epsom in Auckland have concluded in recent elections, voting for Act candidates to ensure strong coalition support for their preferred party, National.
Back in our neck of the woods, Mr Raihania says he believes many Maori voters are motivated less by tactical voting or a party's policies and more by personality and the people they know.
His summation: "I do think Maori have to be more strategic on how they approach the election and not just take things at face value."
