Solomon Islands have yet to register a win in this tournament having lost to American Samoa and Tahiti.
The Pukpuks are undefeated and on top of the table.
But this doesn’t faze captain, Fredson Soakai who guarantees they will cause an upset this weekend.
Boasting one of the biggest forward packs in the tournament, Soakai says this is where the game will be won.
“We know what the Pukpuks are capable of. We’ve watched them play and we’ve picked out their weaknesses.
“It won’t be an easy game for PNG. I guarantee you that."
"For us it’s also about pride so PNG can expect a very physical encounter against us. It will be a good 80 minutes of rugby,” said Soakai.
The game gets underway at the Sir Hubert Murray stadium at 3:30pm.
