SAM Tomkins return to Wigan Warriors for 2016 can not be confirmed for two more weeks, the full-back has revealed.
His move back to England is still dependent on the Warriors securing his replacement, Roger Tuivasa-Sheck.
The Sydney Roosters No.1 has agreed to move to Auckland in 2016.
But under NRL rules, contracts are not registered until after Round 13, giving players a chance to change their mind.
There is no suggestion Tuivasa-Sheck is planning a backflip – indeed, he has denied reports of the sort – but if he did exercise the option, it would prevent Tomkins moving back to Wigan.
“There is still a clause in my contract with Wigan which says my release from the Warriors is conditional on Roger arriving here, as technically, he still has until the round 13 deadline to change his mind,” Tomkins revealed in his column in the New Zealand Herald.
The former Man of Steel says he has been pleased by the reaction at the Auckland-based club since he announced he was cutting short his spell in the NRL after two seasons.
“I’ve been pleasantly surprised by the positive response from club members, fans and the general public,” he wrote.
“Their reaction has been brilliant. A lot of folk that I’ve met on the street or just bumped into have said ‘we’d like you to stay’ but they also understand my reasons for wanting to return home.
“I’ve found a lot of Kiwis are very family-oriented and they seem to understand I’m not leaving for any financial gain or anything like that.”
Tomkins said he began feeling “unsettled” after returning for pre-season following a visit home.
“I never expected I would miss England and the comforts of home, but it took an off-season trip back to Wigan for me to realise this is where I wanted to be,” he added.
