Andy Farrell has made just a single enforced charge to his starting Ireland team to face the All Blacks in Wellington from the side which won the second test in Dunedin last Saturday.
Bundee Aki comes in at inside centre to replace the injured Garry Ringrose. Robbie Henshaw, who played at 12 in Dunedin, switches to outside centre.
With Aki bumped up from the bench, Keith Earls - who captained Ireland to victory over the Maori All Blacks on Tuesday - is among the replacements.

After disappointing defeats to the Maori All Blacks and the All Blacks in the first two games of the tour, many would not have expected the series to go down to the wire. But a historic first victory for Ireland over the All Blacks on New Zealand soil last weekend has set up what should be an epic encounter this Saturday.
"Everyone realises the size of the task in hand, but there's a lot of excitement about being able to deal with that," said Farrell.
"The best part of where we're at is that we know we can do better. What we've done pretty well is have a clear understanding about what our game is all about, and what we need to do to get better. We had a decent result in the last test, but hopefully our best is saved till last.
"The All Blacks have a plan, but it's up to us to make sure that we bring a bit of chaos to that plan. We've got to make sure that we put doubt in the All Blacks' minds as the game goes.
"It really does not get any better for us. We have all talked about playing against the All Blacks when our backs are against the wall or when they have come off a loss and we know what the history has said about all that.
"That is exactly where we want to be. We know they will be hurting. We know they have bounced back unbelievably strong [before]. We have played them enough times to realise what is coming.
"To have them in the last game before we break for another season, when we expect them to be fired up really wanting to prove a point to us and themselves, it couldn't be any better for us. To be able to deal with those situations is exactly where we want to be."
