Piutau set for Wasps stint

The 23-year-old utility back, who will join the Pro12 side next July, will sign a six-month contract with Wasps after being omitted from New Zealand's Rugby World Cup squad.

Ulster are not in a position to include him on their roster for this season as their foreign allocation is full.

Piutau played for Auckland Blues and has been capped 17 times for NZ.

Ulster announced his signing in April in a surprise move, with Piutau expected to re-sign with Blues and New Zealand Rugby.
