The Dunedin Casino is closed today and tomorrow, after it had its licence suspended for failing to take adequate action over a problem gambler.

Christine Keenan turned over $6.6 million at the casino over three years and was eventually jailed for stealing almost $500,000 from her employer to fund her habit.

The Gambling Commission last month imposed a two day suspension, saying the casino failed to comply with the Gambling Act. The Act would have required it to offer information or advice about problem gambling to Ms Keenan.

Several casino staff are still at work today, despite their employer being closed to the public.
