Gallop (24), a semi-professional bowler, is second in the four and in the middle of the triples.
It has been his goal since he moved from Blenheim to Sydney to play for the Cabramatta Club in 2009.
"I moved there to make myself a better bowler to try to make the 2012 World Bowls team," he said.
"I've achieved that goal and it is huge. Now that I'm in the side, I have totally refocused to try and win the gold medal."
It is a goal he has held since the age of 10 when he watched his father, Lloyd Gallop, win his first New Zealand title in the fours.
"Representing your country at the top level is what I have dreamed of since I started playing bowls," Gallop said.
"You can't get any higher than that. It's an absolute thrill to represent your country at such a big level."
Gallop learned of his selection two weeks after playing the Six Nations tournament in Adelaide in May.
"Dave Edwards, the coach, called me and told me I'd made the World Bowls side," Gallop said. "I was rapt."
Gallop attributes his selection to the experience he has gained playing bowls in Sydney for the past four years.
"It's a different level over there," he said.
"It is where the best bowlers in the world go to play. You are constantly playing at a high level.
"The competition week in and week out is so intense. You have no choice but to lift your game.
"It's even hard to win a club championship."
He was a member of the Cabramatta club team that recently won the New South Wales state pennant competition.
"Since I've been there, we have won two Australian premier leagues, the New South Wales premier league and two state pennants."
He flats with Rowan Brassey, who is the other New Zealand representative in the Cabramatta club.
Former World Bowls champion Peter Belliss, Andrew Todd and Canadian Ryan Bester have also played for the club in the past.
Gallop has learned a lot from Brassey, the former world champion. In his prime, he was rated as the best draw bowler in the game.
"Rowan is the perfect guy to try and emulate on the green," Gallop said. "He mentored me through the games when I started playing for the club."
One of his highlights was to win his first New Zealand title in the fours with his father in Dunedin two years ago.
"That was special. We hope to repeat that win at the nationals in Taranaki this year," he said.
"I don't get a chance to play with my old man very often. To win a national title with him was special. I won't forget that."
Gallop became fascinated with bowls from a young age when he followed his father to the green.
He went with the family to the 1998 national championships, when his father won his first title in the fours with Andre Smith, of Blenheim, as skip.
"I was only 10 years old and Dad's team beat Gary Lawson in the final. After that, I couldn't wait to get on to the green and I started fulltime bowls when I was 12."
His father has won 31 Marlborough titles
