The Kiwis followed up their opening 24-10 win over England in impressive fashion, running in 14 tries in a 76-12 win to equal their previous biggest defeat of the Kumuls, a 64-0 rout in 1996.
Stephen Kearney's men ran in eight tries before the break to lead 46-0 and surpass Australia's 42-0 victory over Papua New Guinea in Sydney and were in such command that they were able to rest influential captain Benji Marshall five minutes into the second half.
"It was a good result," said Marshall. "Our forwards were outstanding and the wingers were strong. It was a pretty solid effort.
"We were a bit disappointed last week and I think we've taken some steps to improving. there are still some things we need to work on for next week.
"I thought PNG dug deep and those two tries were like winning the World Cup for them back home."
The Kumuls must now pick themselves up for next Saturday's meeting with England in Auckland.
Captain Paul Aiton said: "We're very disappointed. We just missed something that make us PNG."
