A PNG delegation visited Nuku'alofa in February to assess the local facilities and indicated a willingness to help refurbish Teufaiva National Stadium.
However last month Tonga's Games Organising Committee CEO, Feleti Sevele, said that work was yet to begin and uncertainty remained.
But PNG Sports Minister Justin Tkatchenko said they had not forgotten about Tonga.
Mr Tkatchenko said a submission regarding assistance is ready for the PNG National Executive Council.
