Nonu has admitted that he is unsure if he will see out his current deal with New Zealand.

The centre signed a two-year contract extension in July, but has a clause written in that allows him to leave if he wants to.

"We'll see what happens really, I haven't made a decision," he told Fairfax Media. "I have to make a call next week or something. It's a decision based on what I want to do, and my family, not because of any other player."

Nonu joins back-rower Adam Thompson in publicly admitting that he is considering his future. Coach Steve Hansen refused to be drawn on whether the players would be considered for the All Blacks' winter tour to Europe.

"We'll have to see about that," he said. "Players have to make their own decision, the only thing I'd say is 'Do you still have the desire to wear the black jersey?' If you have, then don't go because you'll regret it."
