At 28 he joined Harlequins for the 2008–09 Premiership Rugby season, and remained with the club until his retirement[3] on a deal reportedly worth £320,000 a year.

[citation needed] Evans graduated to the NZ under-21 and senior Aussie Rules Football sides, competed against state teams and was offered a trial with the Sydney Swans.

He later decided to commit to rugby union and played for the Highlanders in the Super 14 and for Otago in the National Provincial Championship.

In his last game against Wales when he came on as a replacement for Carter, he broke the line with his first touch off first phase to set up Sitiveni Sivivatu for an easy try underneath the posts.

He started at first five-eighth against Portugal in a game which New Zealand won 108–13, and in the process accumulated 33 points via 14 conversions and a try.

He was instrumental in the Harlequins back-to-back defeats of Stade Français in the Heineken Cup and helped salvage a draw for his side in their Boxing Day clash with the Leicester Tigers in the Guinness Premiership.

Whilst in this role, the team won the English Premiership during the 2020-21 season beating Exeter Chiefs 40-38 in the final.
