"We have already seen generous support from the private sector, both in donations and contributions in-kind through the provision of goods and services," O'Neill said.
"The PNC Red Ball for Earthquake Relief will be an opportunity for the People's National Congress Party to bring together our supporters to raise funds for people during their time of need," he said.
The dinner will take place at Sir John Guise Indoor Stadium in Port Moresby on April 14.
O'Neill thanked partners in the business sector and the international community for their "unwavering support" in dealing with the earthquake disaster.
"Companies such as Oil Search and ExxonMobil, and our friends in Australia, New Zealand, China, Israel and many other countries have mobilised and are working alongside our government agencies," O'Neill said.
