Mr Eastwood said he was not told that he was getting the award and happened to be on his feet with a glass of wine when he heard "Northland" in the award announcer's preamble.
"I thought, 'I wonder who's getting that and then he mentioned Otago University and it hit me, he was talking about me - and that in about three minutes I would be making a speech in front of hundreds of people, a speech I was totally unprepared for'," he laughed.
Mr Eastwood said it was great to be recognised by his peers. He has also been congratulated by the Sport Northland board of trustees, especially a proud board chairman, Chris Biddles.
"This is a wonderful achievement for Brent and Sport Northland," he said, adding Sport Northland being a finalist for the commercial partnership award made it "a very good night for Sport Northland".
Mr Eastwood's award includes a grant for professional development.
