Typical tree species are Rimu (Dacrydium cupressinum), Southern Rata (Metrosideros umbellata), Kahikatea (NZ White Pine) (Dacrycarpus dacrydioides) and Kotukutuku (Tree Fuchsia) (Fuchsia excorticata). Understorey plants include Kiekie (Freycinetia banksii), Supplejack Vines (Ripogonaceae), Saw-sedge (Gahnia xanthocarpa), numerous ferns of all sizes, and abundant mosses and liverworts.
