Even if you proportioned the NZRB reserves as per the Racing Act 18 months ago you would have had enough funding to initiate the development of all weather tracks. Unfortunately that money has mostly gone down the stakes gurgler. At the current burn rate there will be nothing left in 18 months. Closing racecourses won't liberate vast amounts of capital.
Shifting race dates away from small clubs to bigger clubs doesn't increase the total stake pool nor increase the number of races or meetings so return to the industry doesn't change. Moving race days to already under stress tracks will raise the risk of abandonments. I doubt Te Rapa can cope with much more for example. BTW a stupid decision to shift Ellerslie race days there while the track is being worked on.
Another problem is with how the stakes are distributed - the stake structure is too top heavy and generally those big stakes end up in the same big stables. In my opinion flatten the structure, take a bit from the top and increase those at the bottom. It won't reduce the quality of the fields in those big races. In fact it is noticeable that while increasing the stakes at the top end we are seeing quality dropping.
Feed the grass roots first.
