Reihana's side suffered their seventh away defeat at Quins
Northampton captain Bruce Reihana has wished his fellow New Zealander Carlos Spencer all the best for the future as he leaves the club.
Fly-half Spencer, who signed in 2005, has left Franklin's Gardens after losing his place in the first team.
"We've been through a lot of ups and a lot of downs together," Reihana told BBC Radio Northampton.
"We've stayed true to the Saints but his time to leave has come, and that's sad because he's a close friend."
He added: "But I wish him all the best for the future."
Reihana's team are still without an away victory in the Guinness Premiership this season after losing 27-6 to Harlequins at The Stoop on Saturday.
Northampton's two penalties came from the boot of Stephen Myler, who has taken over the number 10 shirt from Spencer this season.
