"This is the first winter I've had in about six or seven years, I think," Brown said. "Well it's better in Tauranga than it is in Wellington so I moved up there this year for that reason thinking I was going to be here over winter. So it's a lot more bearable than Wellington at this time of year."
Brown, who has played the Open once before in 2009 but missed the cut, could have gone back to Europe this year and chased some qualifiers to get starts on the Challenge Tour but it was never a realistic option.
He secured his spot in the Open Championship - which starts on Thursday night (NZT) - via a qualifying tournament in Melbourne in January and decided to park up in New Zealand during the winter.
"I just thought I'd stay here and get as fit as I could and work hard on the game and spend some good hours practising. I've managed to do that and I thought that would be more valuable to just feel a bit fresher mentally and physically."
Having not had a full-time caddy for the past two years, Brown will have friend and Tauranga Golf Club pro Jay Carter on the bag at Muirfield Links, a course the 38-year-old has never played before.
"He knows the game, he knows the shots, he knows my game, he's been studying up on the course a little bit so he'll definitely add value and that's what I'll need in this tournament, I think," Brown said of his caddy.
Brown's experience playing links golf on the European Tour should put him in good stead for the Open and he was typically understated as he assessed his chances. He also drew some inspiration from fellow Kiwi Steven Alker who finished in a share of 19th last year after getting a start via a qualifying tournament.
"You're in the field and you've got a chance, you know and you get a good side of the draw hopefully and if you play well there's no reason why you can't have a good finish, Stevie showed that," Brown said.
