Head coach Kristian Woolf said he was pleased with the squad he has been able to assemble.
"We have had a good core of players for the Mate Ma'a Tonga team since the 2017 World Cup and we have been able to add some more depth this year," he said.
"It is going to be a huge occasion coming up against the Kiwis on their home turf at Mount Smart Stadium.
"I know these players and the wonderful Tongan fans are already excited for the event, and this squad will give us every opportunity to perform well in the Test."
The final Mate Ma'a Tonga team to face New Zealand will be named after this weekend's NRL round concludes.
The sides haven't met since the Mate Ma'a Tongan side toppled the Kiwis 28-22 during the 2017 Rugby League World Cup. It was the first time a tier two nation had ever beaten a tier one team, and since then the Tongan side has continued to go from strength to strength.
While not having played against the Kiwis since 2017, New Zealand-based Tongan fans were able to see the side live late last year when they were beaten 34-16 by Australia at Mt Smart Stadium.
