The PNG girls kept the pressure on right from the start and finally broke the defence down in the 30th minute through Jacklyn Maiyosi, who fired one past keeper Karine Xozame.
The lead was pushed out to 2-0 right on half-time, thanks to a well-placed strike off the boot of PNG’s first goal scorer at the FIFA World Cup – Nicollete Ageva.
There was no stopping PNG after this, starting with a goal from Ramona Padio three minutes into the second half.
Ageva then scored three more times in the space of ten minutes as New Caledonia struggled to find answers to stop the onslaught.
It became 7-0 just before three minutes before full time with Maiyosi scoring her second of the match to register PNG’s first win on day two of the Championship.
PNG will meet Tonga in their third match on Monday, July 17, at 10am (8am PNG time).
