Racing 'in doldrums'
Racing is in the doldrums but the New Zealand Racing Board is embarking on a strategy to make it the best wagering organisation in the world, with the highest population rate of participation, NZPA reports.
The Avondale Jockey Club has suspended racing at its track from July 4 because of financial problems and a series of race meetings have been abandoned because of unsafe tracks.
The industry has had to reduce prize money through a Government clampdown on sponsorship through the proceeds of poker machines.
The strategy sets out five goals to achieve by 2015.
• A modern retail network offering the best betting services.
• A world-class betting website, meaning the TAB would be New Zealanders' preferred wagering provider over offshore competitors.
• A customer base of one-fifth of all New Zealand adults.
• Greater funding for the three racing codes.
• More owners of quality horses and greyhounds, with ownership to become more accessible and affordable.
