I think - looks rather like this https://inaturalist.nz/observations/6198241 except specimens a bit far gone... Common under rawirinui (Kunzea robusta) on clay. Colonial. Fruiting bodies often maggot-ridden, immature ones covered in coarse protuberances, mature ones with stipes covered in coarse protruberances, pileus surface and margin also with small pointed protruberances - somewhat slimy.
