Otaki would set the fee so, if you think venue hireage is too low maybe have a chat to them.
I don't know which clubs you are comparing with for fairness. I note Masterton pay $8K venue hire.
Funding is made up of many aspects. I'm picking the $17K is for being a part of the Christmas at the Races model for one of the meetings. The other amounts allocated to funding have been negotiated over the years, you'd have to thrash it out with whoever is looking after that now at club and/or NZTR level, if you are concerned Levin is receiving more than their share. Until recently the LRC ran a Group 1 and two listed races, probably deserving the level of funding received.
