Former All Blacks coach Sir Graham Henry has revealed he called for an investigation into referee Wayne Barnes' performance during the 2007 Rugby World Cup quarter-final.
Henry made the claim during an interview on TVNZ's current affairs show on Sunday, saying it made him physically ill to watch the match against France which the All Blacks lost 20-18.
"We were expected to win," he said.
"You feel empty because there is nothing you can do."
In trying to understand how his team had lost, Henry watched a replay of the game over and over again.
At least 40 infringements committed by the French were overlooked during the match, he said.
"The All Blacks didn't get a penalty for the last 60 minutes of the game and attacked over 70 per cent of that time."
"That's (normally) impossible but it wasn't impossible on that particular day."
Henry says he asked the New Zealand Rugby Union if they could get the International Rugby Board (IRB) to take a closer look at the game.
He also wanted to know whether there were any laws or systems in place in which authorities looked into "bizarre" matches.
Henry told the rugby union it should pressure the IRB to institute an inquiry, according to his soon-to-be-released biography, Graham Henry: Final Word, written by Bob Howitt.
Henry says he was told to shut up or he would never coach the All Blacks again.France went on to lose to England in the semi-finals and South Africa won the tournament.
