SkyCity's rivals say its pokie machines will earn more if Auckland Council heeds calls for a regional sinking lid policy on gaming venues.
In the first of the council's hearings on non-casino venue policy, the Racing Board argued against banning new pokie machines in the central city area around the casino.
For the board, New Zealand Gambling Law Guide author Jarrod True said a sinking lid would not reduce problem gambling.
If a venue closed without being allowed to relocate, he said, addicts would simply head to the next bar.
