Rohan Smith says he has left Bradford because he wasn’t compatible with the new owners of the club.
New Zealanders Andrew Chalmers and Graham Lowe have taken over at Odsal.
Smith will be replaced as head coach, as he is set to return to Australia.
“Having spent a bit of time with the new ownership in discussion, we clearly weren’t compatible and it was certainly in my best interests and that of my family to take ourselves out of contention,” he told The Bradford Telegraph & Argus.
“I love the club and I have done since I was 14 when the Bulls started and I was on the terraces, so I was committed towards staying.
“But the circumstances have changed drastically. I needed to take care of my family and make sure we were happy in our environment.
“I’ve learned a lot and I’ve made a lot of fantastic friendships with staff and players and obviously connected with a lot of fans.”
