He said he was happy as he was not expecting to catch a fish that big.
"It's my favourite sport, something I love doing. It's like an addiction."
Cole said he was surprised and "over the moon" when he won the six national awards, and is planning to display them in his room.
After eight days of competition the Te Kaha Sport Fishing Club was placed second to Houhora.
During the tournament anglers throughout the country tagged and released 142 striped marlin to help marine scientists learn more about the behaviour and migratory habits of this fish species.
