Gambling in New Zealand is controlled by the Department of Internal Affairs. All public gambling is expected to return a portion of profits to the community. The largest proportion of the gambling industry is operated by state-owned institutions. Expenditure on gambling was $NZ 2.034 billion in 2008, a tenfold increase over 1985 figures.

TAB New Zealand, previously known as the New Zealand Racing Board (NZRB) and the Racing Industry Transition Agency (RITA), is a statutory monopoly for New Zealand sports betting, including betting on horse racing and greyhound racing. It was established under the Racing Act 2003 to operate the TAB, promote the racing industry and maximise the profits of the industry. It broadcasts racing on two television channels TAB Trackside 1 and TAB Trackside 2.
