The problem is that NZTR doesn't make a cent out of Kurow or any other thoroughbred race meeting anymore. I remember Greg Purcell pointing out the first time I met him that the most successful meetings thoroughbred racing runs are the ones they don't have. All the money they operate on and distribute to clubs toward stakes and costs for racemeetings are now earned from overseas and sports racing revenue and now RITA are borrowing to provide even that. Integrity costs come from pokies. 12 years or so ago, they pretty much payed their own way.
Unless they get a more self-sufficient business model in place then soon it won't really matter how many people some clubs get on course, how good their tracks are, or all the volunteer contributions or whether new people are attracted to the game. There just won't be one.
