The future of greyhound racing is uncertain after a new report on the industry is before Cabinet.

Racing Minister Kieran McAnulty has read through the report from the Racing Integrity Board, but won't be able to present it until February.

He says they could put the industry under strict monitoring, or shut it down entirely.

Greyhound Racing New Zealand CEO Edward Rennell told Tim Dower they've made significant improvements since the report was commissioned in September last year.

He's confident they can demonstrate they've made appropriate changes, and that animal welfare is paramount.
