While doing some research into the amount of funding withheld from Awapuni, I noticed with interest the way these Dunstan races are funded. These races are all worth $5,000 more than the norm and I always assumed the sponsor tossed in the extra. This isn't the case at all. I see NZTR actually contributes the extra $5,000 to each race, so $85,000 over the 17 heats. For the final, NZTR contributes $70,000 as normal funding, plus an extra $10,000, and the club, presumably with sponsorship included, contributes $40,000.
I'm sure the sponsor does contribute some money to the clubs holding the heats, but none of it goes towards the stakes. NZTR contributes an extra $95,000 to this series.
I'm not saying this is a good or bad thing, I just find it interesting all the extra funding NZTR tosses into random races, usually hosted by the favoured clubs.
