Steve Hansen says he did not meet second Test referee Romain Poite before the Wellington Bledisloe Cup match but the ARU is still seeking clarification from World Rugby as to why Michael Cheika was not extended an invitation to a meeting with Hansen and assistant referee Jaco Peyper.

The ARU announced shortly after the Wallabies' 29-9 loss in Wellington it planned to make an official complaint to World Rugby's integrity unit about a supposed meeting between Hansen and Poite.

Hansen said the claims were false and revealed it was actually assistant referee Peyper, who was in charge for game one in Sydney, that wanted to catch up before the Test.

"It's quite sad that's come out, isn't it, because it's not true," Hansen told reporters on Sunday. "[I said] g'day to Romain in the morning, he stayed here at this hotel. But I did have a meeting with Jaco Peyper this week at his request. 'Crono' [All Blacks scrum coach Mike Cron] and I both got asked by him to review some of the stuff that he had seen in our game. I'm a firm believer that we're here to support the referees and help them. It's a difficult game to ref so why wouldn't you have the meeting?
