Kiwis pulling plug on pokies

New Zealanders are gambling less in pubs and clubs, with poker machine revenues falling for the third year running, figures show.

The Department of Internal Affairs figures - taken from electronic monitoring of gaming machines in the country's 1455 pubs and clubs - showed the number of licence holders, gambling venues and gaming machines also dropped.

A total of $849.2 million was spent on the pokies in the year to June 30 - down 4.5 per cent from $899m in the previous year.
