Following 18 hours of play over two days, Tamihana found himself heads up against one of New Zealand's most successful tournament players, Jackson Zheng.
And on their final hand, Tamihana needed a little luck to get the job done. Zheng was all in with 94 on a 10 9 2 board against Tamihana's 25, but when a 2 hit the turn and a 10 on the river, the title was Tamihana's.
The duo outlasted a field of 108 players that all bought into the tournament for $1650, generating a prize pool of $178,000.
Tamihana, a Hawke's Bay local who often travels to Auckland on weekends to play in the countries highest limit Omaha cash games, said his tactic was to pick on the big stacks, and make people feel uncomfortable.
"I think I'll claim it as back to back titles, cause we didn't play it our last year," Tamihana said.
"I got a bit lucky on the turn against Jackson but I was just trying to put him under pressure. And winning tournaments is 90% about luck."
What next for Tamihana?
"I'm heading down to Christchurch next week for their series, but right now I'm going to have a few beers to celebrate and might even get back into the cash games. Some of the pots are bigger than tonight's first place prize."
