An inquiry into the welfare of greyhounds will be undertaken by the New Zealand Racing Board.
The inquiry will be carried out by former High Court judge Rodney Hansen and will review breeding and racing practices, life-cycle tracking of New Zealand-bred and imported greyhounds, and what happens when the animals are retired from racing.
However, it won't be open to public submissions.
New Zealand Racing Board chair Glenda Hughes said, since a select committee review three years ago, the greyhound racing industry has made progress in the protection of dogs.
She said the inquiry would look into whether there was a need for further review and whether there was any need for improvement.
The inquiry is due to completed by the middle of next year.
