New Zealand scrum-half Jimmy Cowan has decided to call time on his spell with the Highlanders to join Gloucester next season.

The 30-year-old has been with the Otago outfit since 2003 and has recorded over 100 appearances for the Super 15 club, which he will leave at the end of the current campaign.

Having seen Piri Weepu and Andy Ellis preferred in the No.9 jersey for the All Blacks in recent outings Cowan, who helped New Zealand lift the Webb Ellis trophy in last year's World Cup, has decided to take up the opportunity to play abroad and has chosen a move to the Aviva Premiership with Gloucester.

The 51 capped New Zealander has been a loyal servant to the Highlanders and their head coach Jamie Joseph has hailed the half-back for his efforts with the club from Southland.

"Jimmy has been a player who has always given his all on the field and I'm sure he will continue to do so in the future," he said.

"As one of only two players to play 100 games for the Highlanders he leaves behind a significant legacy."
