This goes back several decades, Chief. Its not recent.
Look back at renovation of Greymouth. Canterbury grass sown under advice from the CJC track manager, Max Skelton ( for one) sustained severe injuries when his horse slipped over.
Gore redone, horses fell over, Terry Moseley slipped twice at the same place on the same day!
Rangiora renovated. That disaster has been discussed at great length, hasn't raced since.
Riccarton itself, remodelled, although it is still operational the surface has been criticized ever since. It gets away with less than perfect because it is a large circuit with sweeping turns.
You'll sneer and say I'm dredging up ancient history. But the facts are there, NZ racing has a history of botching renovation.
