I was interested to read the Victoria end of season review of AWT racing and their future plans for that. https://www.racing.com/news/2022-08-31/news-industry-synthetic-season-by-the-numbers
It seems they intend to continue reducing AWT programming primarily because of participant preferences for more grass racing instead. In similar climatic conditions it also seems likely that a reapplication of binder and wax will be required here after 3 years of use in order to mitigate the kick back issues. It also seems that full resurfacing is likely to be required after 6 or 7 years rather than the 10 years mooted. To date, I am yet to see from NZTR or the clubs concerned, any sort of plan as to how this maintenance will be funded.
It seems likely that Victoria may replace the AWTs with second grass tracks as part of a 10 year plan, certainly in the Pakenham case. It would be interesting to know if NZTR might have similar plans here for the Riccarton and Awapuni ones and if they similarly expect to reduce the AWT racing in the intermediate term. The Victoria experience and strategy seem like a good model to follow for that.
In the mean time, the AWTs should continue to provide a decent surface for trackwork, trials and racing for another couple of years.
