And the man who helped organise the trip, Matt Blair, will himself be the trainer for the Tongan side when it plays in the tournament.
Body, the trainer for the Zingari-Richmond premier side, and Puckett, the University A trainer, will leave for Tonga next week to spend more than five weeks training the 40-man national squad.
They will be involved in the physical preparation of the team, along with nutrition and off-field training.
Blair, a lecturer at the Otago Polytechnic Institute of Sport and Adventure, got a call from former Highlanders No 8 Isitolo Maka last month to ask if he could assist with training the team in preparation for the World Cup. Blair was involved with the Highlanders when Maka played for the franchise.
Due to work and family commitments, Blair could not commit himself for the whole period and organised Puckett (35) and Body (37) to get involved.
"It is a huge opportunity for these guys and they are champing at the bit to get over there. In some ways the club season these guys have had meant I knew they were the right fit. They have been through the rough stuff and are prepared to work hard," Blair said.
Blair (41) will spent the first week with the duo and the team before returning home.
He will then return just before the World Cup as Tonga gets ready to face the All Blacks in the opening game of the tournament on September 9.
"It is going to be an amazing experience really. To be at Eden Park in that first game will be quite a privilege."
Blair is also helping monitoring the fitness of the referees at the tournament but said that would not be too much of a distraction.
Tonga had a competitive side, losing just one game in the Pacific Nations Cup to eventual winner Japan.
It has players spread all over the world and the players from northern hemisphere clubs are being released next week for the training camp. Along with Maka, former Wallabies No 8 Toutai Kefu is involved in coaching the Tongan side.
Blair said funding for the coaching and preparation came from the IRB and he said it would be an unique experience.
"We'll be looking at using things like coconut milk as part of the recovery drinks and there should be plenty of that available."
