He began game fishing when he was 10 and hauled in his first marlin soon after.
He modestly said making the catch was "pretty cool" and he was surprised to catch the spearfish as it was unusual for this time of the year.
The fish wasn't just a pretty face either - it was later smoked and served up for dinner.
Ezra's uncle Zac Holmberg was on board when the mighty catch was reeled in.
The day had been underwhelming before the catch: they were about 40 nautical miles offshore, the conditions were rough and they had missed snagging a blue marlin.
But at around 3pm, Ezra's line got a bite and it was all on.
Ezra was "stoked" with the catch and it was the biggest catch of the day at the club, Holmberg said.
It was chucked in the chiller overnight and it was weighed up the next morning.
"The weighmaster said it was the biggest [spearfish] he'd ever seen," Holmberg said.
Tauranga Sport Fishing Club manager Roly Bagshaw said it was great for the club to see a young person coming up through the ranks.
"It's an amazing fish to catch for such a young angler."
