SkyCity Entertainment narrowing its underlying proft guidance as a boost from incoming tourists comes alongside higher legal and compliance costs.
The company has trimmed its earlier guidance of between $305 million and $320m to be between $300m and $310m.
Ahead of the company's investor day in Auckland, the company said rebounding tourism numbers were boosting patron numbers and electronic gaming machines were still popular, though the severe weather in the supercity partially offset this.
However legal and compliance costs were higher, partly due to increased efforts around anti-money laundering and harm minimisation, the company said.
The investigation into the suitability of SkyCity's Adelaide to continue to operator continued, but an independent review into the casino was pending until the completion of court proceedings against the same casino.
Those proceedings against the casino had been brought by the Australian Transaction Reports and Analysis Centre - AUSTRAC - relating to alleged breaches of anti-money laundering laws, involving as much as $4 billion and potential fines of tens of millions of dollars, which were still before the court.
SkyCity said further meetings on the issue were expected in late May or June this year.
