The Solomon Islands government is giving a partly Australian-owned casino in Honiara until November to comply with gaming laws.
The licence for Solomon Islands Casino is one of two casino licences allowed for Honiara.
But the casino has not fulfilled the legal requirement for it be attached to a hotel.
Meanwhile, the Papua New Guinea-based developer, Kostas Constantinou, says he remains optimistic that the proposed five star hotel development will get a casino license.
A spokesperson for the developer says the hotel requires up to 50 poker machines to be installed, and it will continue to lobby for a third casino licence to be issued.
The PNG developer says the gaming room is essential for the hotel, and it has already spent millions of dollars on the proposal.
The government has not made any amendments to the Gaming Act.
The commerce minister, Walton Naezon, says the government is backing the PNG hotel developer's proposal.
