Wairarapa's "sinking lid" gambling policy has seen a more than 20 per cent decrease in the number of pokie machines across in the district.
All Wairarapa councils have adopted the policy, which means no new gambling venues or gaming machines are permitted and machines that have not been used for six months cannot be reactivated, replaced or transferred to a new site.
Carterton District Council last week adopted a reviewed but largely unaltered version of the 2012 Wairarapa Gambling Venues policy, with attached reports showing the number of pokies last year had decreased to 188, down from 240 in 2011.
In a report to the council, Carterton's planning and regulatory manager Milan Hautler noted the reduction of gambling machines and venues "indicates that the sinking lid approach is helping".
Masterton remained the area with the most pokie machines, with 78, while Carterton had 45 and South Wairarapa 65.
