A revised design for the controversial SkyCity convention centre will be completed by the end of next month.
"The Crown and SkyCity have been making good progress discussing a revised preliminary design," Economic Development Minister Steven Joyce said.
"This is a large and complex project. There are some matters that need resolution before the revised proposal is submitted for approval by Ministers and the SkyCity board."
The casino operator had submitted a design in October last year, but when total construction costs exceeded the agreed $402 budget it pushed for a taxpayer contribution.
Prime Minister John Key initially suggested that could happen to avoid the construction of a possible "eyesore", but the Government later agreed the initial budget of $402 million should be stuck to.
