I understand that part of any such move to us would allow the NZRU more say in the terms, such as a fixed contract with a veto over an extension thereof if they deem the player was required back in the NZRU fold in the run up to the next RWC, potential to have them back if required for short term loan due to injuries, etc, which they wouldn't be guaranteed otherwise. They'd no doubt also be able to have an input into his training off season.
