Wallabies coach Dave Rennie has hit out at Rieko Ioane for "mouthing off" during the first test, saying the All Blacks midfielder accused Australia of disrespecting the haka.

Rennie was typically forthright on a number of topics after naming his team for the second Bledisloe Cup clash at Eden Park on Saturday, adding further spice following a contentious opener in Melbourne.

The Wallabies, like many opposing sides, responded to the haka before the first test by grouping together and advancing. While those actions created no apparent controversy at the time, Rennie today revealed that Ioane had taken exception.

"Rieko Ioane had a lot to say to our boys after the final try, mouthing off at Folau Fainga'a around disrespecting the haka," Rennie said. "Which is a bit odd because as New Zealanders would know, when a team does a haka, you respond with a haka.

"We don't have the luxury of having a haka so our response is in the boomerang shape and to move forward. They've thrown down a challenge and we're accepting it.
