I dont have all the answers but a few things spring to mind.
I think we have to many race meetings in a week...sometimes 3 on a Saturday...hard to get jockeys at two let alone 3...cut the meetings per week down as like the old days and that in itself would increase stakes a little.
2 Fix the programming its a diabolical mess at the moment..especially the SI, geez what's the point of having a 2yo down there you get maybe 3 or 4 chances to run in a season its a joke and the whole calendar needs looking at and be programmed by someone with knowledge of actually how often horses can run.
3 Cut NZTR costs, they are through the roof and keep getting worse, its a joke and nobody seems to try to fix this...way out spending its means.
4 Have a student type academy set up so Jockeys, strappers and trainers can be trained from the start, get the kids interested in High school so we have a pool of talent to get people from.
5 have a tax on selling horses offshore...so we dont simply lose our best before they even race, this has been a drain on our industry for the past 25 years or more.
6 Put people who know and understand racing in charge of it in all areas not wankers with a suit and a CV from some big wig company...thats who is stuffing us now...Sharrock aside.
