Until the end of last year, Sitiveni Sivivatu matched Joe Rokocoko's test try scoring rate.

The Fijian flyer had averaged a try a game in his 21 tests and has given the All Blacks a lethal threat on both flanks since becoming an international player in 2005.

Whether it has been the new rules, several leg injuries, tactical changes or plain circumstances, Sivivatu is not certain why he has bagged only two tries in eight outings this season.

Sivivatu has undergone some intensive training for the past few weeks after injuring his ankle during their game against the Springboks.

He has been the go-to wing for the All Blacks this year with Rokocoko sidelined because of a wrist injury.

Wallabies take on the All Blacks tomorrow night at 10.05pm in Brisbane.
