"The great thing is, looking at all those players that hadn't played in the first game, there is a bit of pressure there for spots and competition.
"Te Maire wants it for sure but we have just gone with Kodi because we think he can direct the team with Shaun and he has that little bit of x-factor about him and confidence."
Kidwell played down any thoughts of the occasion being a grudge match against those Tongan players that turned their backs on the Kiwi jumper just prior to the World Cup.
He insisted that won't impact on how the Kiwis approach the game.
"We are in a really good space - we have been since the start of the campaign," the Kiwis coach said. "We are nice and relaxed but we also know the big challenge ahead of us.
"We just have the focus on us and our energy and where that needs to be.
"We aren't tapping into any emotion or anything. We are preparing how we have been for the last three weeks since we started the campaign."
Tonga has been impressive in their back-to-back wins so far this tournament. They thrashed Scotland first up before a dominant win over Samoa last weekend.
Kidwell and the Kiwis have watched both Tongan games and were impressed by their performances.
"They have been playing great," he said. "They had a good game against Samoa. Their strengths I think are in their forward pack so our forward pack is looking forward to the challenge."
The big test will be trying to keep 2016 Dally M medal winner Jason Taumalolo in check.
"It is about limiting his metres," Kidwell said. "He is obviously the form forward in the game but I look at our forward pack as well and the way we have been performing.
"We just have to make sure we prepare well during the week and are ready to face that challenge."
