Maori Affairs Minister Pita Sharples says the Maori Party will oppose any expansion of Sky City's casino operations.
Dr Sharples says he has told Prime Minister John Key of his strong opposition to a deal being proposed in exchange for the company building a new convention centre in Auckland.
He told Waatea News he does not accept Mr Key's argument that having more pokie machines and gaming areas will not worsen problem gambling.
Dr Sharples says he has been trying for years to get a combined convention and Maori cultural centre built on Auckland's waterfront.
