Crusaders coach Scott Robertson says he wants the All Blacks head coaching role or nothing at all.

Robertson is one of the front-runners to be the next All Blacks coach and has confirmed he has his job interview with New Zealand Rugby lined up for December.

The Super Rugby title-winning coach said he only had interest in the All Blacks top job and would not consider an assistant role with the national side.

New Zealand Rugby reached out to 26 prospective candidates to replace outgoing coach Steve Hansen.

Robertson said he was currently "doing two jobs" as he prepared a new-look Crusaders for a Super Rugby title defence as well as got himself ready to face the All Blacks coaching appointments panel.

Should Robertson be named as All Blacks coach he said he would leave the Crusaders after three years in charge.

To fill the void, Robertson said the Crusaders, who kick off their Super Rugby campaign on February 1, had a plan in place.

However, Robertson would not confirm if the Crusaders head coach role would then be passed on to one of his current assistant coaches.

Robertson had reached out to Japan assistant coach Tony Brown to join his coaching team but the former All Black turned him down, opting instead to back Japan coach Jamie Joseph in his push for the All Blacks role.

The appointment panel includes incoming NZR chief executive Mark Robinson, NZR head of High-Performance Mike Anthony, former All Blacks coach Sir Graham Henry and former Silver Ferns coach and High-Performance Sport New Zealand director, Waimarama Taumaunu.

Around 12 players would also have input on the appointment.
