A New Zealand Air Force Hercules will fly in emergency supplies for victims of the severe flooding in Papua New Guinea's Oro Province this weekend.
The confirmed death toll from the disaster is 164 while thousands of people remain homeless.
The New Zealand Foreign Minister, Winston Peters, says the plane will deliver two generators, tarpaulins, collapsible water containers, and 500 blankets following a request for assistance from Papua New Guinea.
He says the supplies, from stockpiles held by the government's aid agency NZAID, will help thousands of people in the affected area, who desperately need shelter and clean drinking water.
The plane is due at Girua Airport near the main town in Oro, Popondetta, on Saturday.
The contribution from New Zealand comes after an initial 75 thousand US dollars last week soon after word of the extent of the disaster was revealed.
Mr Peters says more help will be sent if PNG officials ask for it.
