The All Blacks could be all black once again, with speculation the famous jersey's white collar is facing the axe.

Adidas New Zealand confirmed last night a new All Blacks kit would be revealed on Wednesday week at a special function in London.

The team, which left New Zealand yesterday for their northern tour, are due to debut the new playing threads in the Twickenham test match against England on November 9.

Confirmation about the new kit followed a tweet from adidas last week which featured a photo of skipper Richie McCaw in a new all-black jersey.

It appeared to have no white collar, which was reintroduced to the uniform for the 2011 Rugby World Cup as a throwback to the jersey worn when New Zealand had last hosted and won the tournament in 1987.

Before the World Cup strip, the jersey had a black collar - brought in by adidas when it took over from Canterbury as the All Blacks jersey maker in 1999.

Adidas would not confirm if the white collar had been dropped from the team's new strip last night.

"There have been a number of design and performance enhancements made to the new All Blacks kit and all will be revealed on November 5," manager for adidas New Zealand Quentin Bleakley said.
