This is the same patch as the seen two weeks ago (in this observation). Jerry Cooper's current ID on that observation is Amanita excelsa ssp. spissa. I've collected a sample.
By Pinus radiata.
I think this might be Straw flycap (Amanita australis). It seems to fit the descriptions quite well. Although it was growing in oak dominated forest at Victoria Park, there was also a lot of kanuka and manuka around which I believe to be two of the native species this fungi associates with.
