A lot of the tracks are off limits anyway,I think in reality a lot of hot air will be blown around,probably fuck all changes more likely but in cases changes are needed,its been happening for a long time anyway,Tapanui,Westport,Rangiora,Nelson,Orari,Winton,Wyndham and recently Waikouiti,Hokitika and Banks Peninsula and Waterlea and Omakau ,one or two of those may have a case for resuming there is only so far you can reduce,will Timaru,Oamaru,Gore,etc etc go,I'm not so sure.
Forgot to mention Waimate who should at least get their trotting day back.
