The NRL halfback moved to the Sharks in the off season after asking for a release from the Mount Smart Club with a year still to go on his contract.
Speaking to Inside the NRL, Johnson was asked in a fan-submitted question over the possibility of a move back across the Tasman.
He says he would never burn any bridge, so if he was offered a contract and it was the right decision, he would move back, definitely.
The sentiment wasn't the same when Warriors coach Stephen Kearney was asked a similar question earlier in the season.
Kearney told reporters 'that ship has sailed'.
