Racing Minister Winston Peters has confirmed he's in no hurry to make a call whether or not to ban greyhound racing.

Appearing before a select committee, Peters claimed he wanted to wait at least a year to make a decision - and had no interest in making a 'careless' choice.

Peters says he ran the risk of being called to account if he rushed the process of a potential ban.

"I've got people surveying the scene on a weekly basis, finding out what is happening and whether there are improvements - and in a time, very soon, in the next few months, we'll have a very clear picture."
