He said there was no direct correlation between gaming machine numbers and problem gambling rates, and that people were turning to offshore and online forums instead.
"Between 2006 and 2010 the problem rate increased, despite the number of gaming machines in New Zealand falling considerably in the same period," he said.
"Between 2010 and 2012 the problem gambling rate stayed the same, despite a continual decline in gambling machine numbers.
"The reasons for an increase or decrease in problem gambling is complex and multifaceted, not simply the direct byproduct of an increase or decrease in machine numbers."
Mr True said a formal relocation provision, part of the NZ Racing Board's submission to TDC, would allow venues to move away from high-deprivation areas to more desirable areas such as CBDs and commercial zones "without losing their ability to host the same number of machines".
"Allowing relocation enables gaming venues to move to new, modern and refurbished premises," he said.
"Allowing businesses to upgrade their premises and provide a more modern, attractive offering to the public helps to revitalise the business districts."
