Warren Gatland not only knows when the All Blacks were last beaten by Wales - 1953 - but the date and year that the men in black last lost at Eden Park.
It was, he said, on Friday, June 11, 1994, when France won a match featuring a try from the ages scored by fullback Jean Luc Sadourny. Saturday's first test between Wales and the world champions just happens to fall on June 11 and former All Blacks hooker Gatland will take all the omens and good luck charms he can get.
He also knows that if Steve Hansen's men are vulnerable at any time, it is in the first test of a series. Gatland watched the All Blacks' first World Cup pool game against Argentina with interest because Hansen's team had to fight back from a fair bit of adversity at Wembley that day. Having two senior men in Richie McCaw and Conrad Smith in the sinbin didn't help, but they were a little rusty, just as they were in June 2014 when they had to fight all the way to beat England at Eden Park in the first of a three-test series.
Gatland has also taken comfort in the way his team performed at the World Cup. Although they went out at the quarter-final stage with a defeat to the Springboks, they were leading for most of the match. A week earlier they went close to Australia in their final pool game.
The All Blacks, meanwhile, sneaked past the Boks 20-18 in their semifinal and the Wallabies kept them close before Hansen's men drew away to win 34-17.
