Eyewitness accounts state many people were not allowed in through the gates because their tickets were not genuine as they had been bought off the streets.
The Games Organising Committee (GOC) said a response would be made later today over these reports.
The PNG National Rugby Rugby Football also commented, saying they were not aware of the reports of fake tickets being sold.
"Tickets were sold only at Stop N Shop outlets and nowhere else. People should not have been buying off the streets.
" But we do know that grand stand and outer stand tickets were bought in bulk and sold at black market prices at K50 to a K100, " said the PNGRFL.
