Wasps have eased their injury worries with the signings of New Zealand World Cup winner Piri Weepu and Martyn Thomas.
Weepu was part of the All Blacks side that clinched the 2011 World Cup on home soil and has 71 Test caps to his name.
The 31-year-old will compete with Joe Simpson at scrum-half, following injuries to Charlie Davies and Jack Moates.
Weepu had been playing for fellow Premiership side London Welsh, but was released from that contract and will join Wasps ahead of his move to Oyonnax next season.
"I'm really excited about joining Wasps before I head to France next season," Weepu told the club's official website.
"I have enjoyed my time with London Welsh in what is a very attritional league this season and I'm looking forward to helping Wasps as they battle it out at the top-end of the Aviva Premiership."
Wasps, who are seventh in the Premiership, also welcome full-back Thomas into their ranks.
The Welshman will add numbers to a backline shorn of the likes of Will Helu, Alapati Leiua, Chris Bell and Andrea Masi.
