SkyCity could be forced to cough up millions for alleged breaches of legislation on money laundering.

The Department of Internal Affairs is accusing SkyCity of violating the Anti-Money Laundering and Countering Financing of Terrorism Act, after a company review.

NZ Herald property editor Anne Gibson says SkyCity will be more concerned about the hits to their reputation, over a prospective fine.

"This is quite damaging to them, it's not so much about the fine- if there is one."
