Stewart said the K33 million given by the National Government to accommodate and feed participants from the 22 Pacific island nations was insufficient.
Stewart told that to the media during a visit to Tambul district, Western Highlands, last Thursday.
Hew was with his marketing manager Ken Siminji carrying out awareness about the Games.
He said the K800m allocated by the National Government was being used to build infrastructure, inlcuding the Games village.
Stewart, who has vast experiences in running Commonwealth Games in India, the Olympics in China, said his committee would raise the K67m they needed outstanding through sponsors and fundraising activities.
“I am very confident that we will find the rest of the money to look after the participating nations in terms of accommodation, food, transport, medical expenses and other costs during for the duration of the Games,” he said.
He told a large crowd at Purare Primary School during the 10th Grade 8 graduation that the 2015 Pacific Games was very important for the country.
Stewart said the Games would send a clear message to the outside world about the country.
He said the Games would be used to market Papua New Guinea to the rest of the world to prove foreign media wrong about the country wrong.
He said the country would benefit greatly from the Games in terms of business activities and tourism.
“The Games belong to you people and you all must feel proud of it because it unites all the Pacific islanders as one people,” he said.
Stewart said there were plans to put up large screens in all the 22 provincial headquarters for people to watch Games live.
He said preparatory work was now progressing well and he expected all the infrastructure to be completed on time.
He thanked the National Government for releasing money on time.
