According to the Gambling Act, 37 per cent of gaming machine proceeds must be returned to the community.
Mr Pollard also said monthly meetings discussing gambling "harm minimisation" policies were held by Trust House managers.
Meanwhile, the number of pokie machines and gaming venues in Wairarapa also dipped slightly in the year to March, the figures show.
Nationally, an overall decline in pokie machine expenditure, licence holders, gambling venues and gaming machines is being applauded by New Zealand's anti-gambling foundation.
Licence holder numbers fell from 359 to 353, venue numbers dropped from 1403 to 1367, and the number of gaming machines declined from 18,001 to 17,542.
Problem Gambling Foundation chief executive Graeme Ramsey believed the decline was largely due to people's growing awareness of the harm caused by pokies.
"What it's telling us is that the trend that we've seen for some time - albeit with a couple of minor blips - is still continuing," he said.
"That's good news and I think it's indicative that people are more aware of the dangers that pokie machines pose."
However, pokie addiction among young New Zealanders was an increasing concern for the foundation.
"Younger people can think that because they are good at [computer] gaming they will also be good at gambling on pokies, especially where these have similar graphics to the games they are used to playing."
A "big win" can draw a young player in, she warned. APNZ
