"After two solid performances against Fiji and Samoa, we have selected a side to play Australia that in some cases is based on form, and in others on giving those returning from injury a final opportunity to press their claim for selection.
"Ezekiel Lindenmuth, Pouri Rakete-Stones, Isaia Walker-Leawere and Ere Enari earn their first starts of the Oceania tournament and will no doubt be keen to make an impact. Captain Luke Jacobson will be joined in the loose trio by Dalton Papali'i and Tom Christie. All three players have big engines and are smart rugby players, both on attack and in defence.
"The back three combination of Will Jordan, Josh McKay and Tima Faingaanuku brings a good mix of speed and power, with Caleb Clarke adding punch from the bench in the second half."
The 28-man squad for Georgia will be named next week.
Australia have laboured to 43-20 and 32-24 victories respectively over Samoa and Fiji, so New Zealand should be warm favourites to gain a small measure of revenge for their 2016 reverse.
There is no TV coverage, but all games will be live streamed on www.rugby.com.au and www.oceaniarugby.com. Kickoff for the NZ-Australia game is at 9pm NZT.
