You don't know his personal situation though. What if it's something like he has a terminally ill parent in Auckland that needs care?
Could be many different reasons.
Nobody in a current first choice 17 would ask to go there for an opportunity so it would have to be a personal matter.
But if it's so pressing why would priority 1 be Warriors contract.
If it is urgent then ask for leave to go and then worry about trying to organise something. You wouldn't keep training with Sharks hoping they might agree to release you (likely after extensive negotiations with Warriors) if it is so urgent.
Maybe he is in Auckland right now, but last we saw he wasn't.
Could also have gone over xmas/new year break and asked for a release on return I guess, but again if he is only willing to go if he can get a contract it isn't that urgent.
Fwiw: Think he is/has been in NZ for his brother's wedding recently.
Caleb is also contracted to us though (train and trial)
And lived with him as of early last year although that may well have changed now (but also given Caleb has yet to secure a full NRL contact decent chance it hasn't changed). So going to NZ for his wedding doesn't really correlate to a request to shift there.
