The Papua New Guinea Prime Minister, Peter O'Neill, says Port Moresby residents don't need to worry about petrol supplies, as other distributors are stepping in to meet the demand.
PNG's major fuel supplier, Puma Energy, says a lack of US dollars has forced it to limit Port Moresby's petrol supplies.
The company has warned of continued shortages over the next few days and other products will be affected if a resolution is not reached this week.
Peter O'Neill says sufficient supply of fuel will be facilitated through other fuel companies, such as Mobil, increasing their deliveries to Port Moresby.
"There is enough fuel in Port Moresby to meet the demands of it's residents. There is no need for people to be up and about, about the consistency of their supply. There is no need for us to have long queues, there will enough fuel in the city to meet the demands of everyone."
Peter O'Neill says there are ongoing disputes with Puma Energy regarding outstanding duty and tax, and some issues surrounding the transferring of their funds out of the country.
He says these concerns are being adequately addressed by customs officials, and the central bank.
