New Zealand's defeat to Australia last year still hurts admits All Blacks assistant coach Ian Foster

New Zealand assistant coach Ian Foster admitted that the All Blacks' defeat to Wallabies in October last year is still hurting the team as they head into the Rugby Championship 2018 opener against the same opponent on 18th August in Sydney.

The All Blacks managed to win both the Rugby Championship encounters against Australia last year that saw them retain the Bledisloe Cup but lost the dead rubber in Brisbane with an 18-23 margin.

The defeat also ended a seven-game winning streak of New Zealand, who still have a huge hold over their trans-Tasman rivals having won 15 out of the 19 games between the two teams since the 2011 World Cup.

"I try to move on, but it is still there," Foster said.

"We saw that after the game, how much it meant to them. It still hurts."

New Zealand have a dominating record against Australia having won 111 games out of the 163 played and will be hoping to win their third consecutive Rugby Championship tournament that also involves South Africa and Argentina.

Despite, the numbers on their side, Hansen believes his team will be the underdogs when they meet in Sydney next Saturday.

"We lost to Australia the last time we played them, so no doubt they'll have a lot of self-confidence and are worthy of starting as favourites," Hansen said on Monday.
