Provincial Rugby Berquist attended the
University of Otago and represented
Otago in 2003 and 2004. In 2005, he transferred to
Hawke's Bay where he would blossom as a player, helping the Magpies turnaround from perennial struggles to
Air New Zealand Cup semi-finalists in 2008 and 2009. During this time, Berquist earned a reputation as one of the best goal-kickers in the competition, finishing as the Cup's leading scorer in 2009. For the
2010 ITM Cup, Berquist transferred to
Auckland. He again topped 100 points in the competition, including finally scoring his first provincial try in his 8th season in the competition.
Super Rugby Berquist was initially a member of the
Highlanders in 2004 while still playing for Otago, but he failed to see action in a single game. Berquist's strong performances for Hawke's Bay earned him a
Super 14 contract with the
Highlanders for the
2009 season. After starting the season as a bench player, he started 6 of the final 7 matches of the season at his preferred position of
fly-half. He shared goal-kicking duties with
Daniel Bowden and finished the season with 49 points, including his first try in Super Rugby. For
2010, Berquist faced increased competition for the starting fly-half position with the Highlanders from
Michael Hobbs and
Robbie Robinson, although he still managed to match his 2009 total with 6 starts. His goal-kicking opportunities decreased from 2009 due to the emergence of
Israel Dagg as one of the top goal-kickers in Super 14. In
2011, Berquist was back up for
Dan Carter at the
Crusaders.
European Rugby Berquist signed for
Leinster Rugby for the 2011–12
Pro12 season. He was to play back up to
Johnny Sexton. He spent almost his entire first season injured which allowed
Ian Madigan to emerge in his absence. His contract was not renewed after his first season. He joined
Biarritz in the summer of 2012 but similarly struggled to get any game action. Berquist joined
Benetton Treviso in the summer of 2013. == References ==
