All Blacks coach Foster hits back at critics after South Africa win

All Blacks coach Ian Foster has called criticism of his team selections "insulting" after New Zealand ended a dismal run with a 35-23 win over hosts South Africa at their Ellis Park stronghold in Johannesburg on Saturday.

Foster has been under intense scrutiny as a result of his team's poor form following five losses in their last six matches, with questions raised about the head coach's future ahead of the meeting with the world champions.

South Africa had recorded their biggest win over the All Blacks in 94 years in last week's meeting, but a strong performance in Johannesburg saw Foster's side turn the tables, prompting the coach to fire a broadside towards his detractors.

Stress "comes with the job. It has been pretty vicious," Foster said.

"There has been a lot of onslaught particularly from our New Zealand media. They've got high expectations of us and they've made that loud and clear. They've clearly come very, very strong at me as a person.

"Some of them have even called our selections popgun, which I found quite insulting for players that give everything to play for their nation.

"That pressure has been strong but it doesn't change the fact that through adversity that's the best teacher for character and we've stayed tight."

Last weekend's loss to the South Africans had been preceded by back-to-back defeats by Ireland as the All Blacks lost a home series for the first since the start of the professional era.

That sequence of results, coupled with losses to Ireland and France on tour in November, had increased the pressure on Foster as the countdown towards next year's World Cup continues.

"It's hard to win all the time and if everyone knew the formula of how to do that we'd all be doing it all the time," said Foster.
