Heritage sites
Historical sites in Mangōnui today are reminders of Maori settlement prior to European contact, and are significant to local iwi, Ngati Kahu.

Located on the Mangōnui waterfront is a beautiful historic kauri building, the Mangōnui Courthouse.

Taumarumaru Reserve encompasses three pa sites historically significant to the early Ngati Awa and later the Ngati Kahu people – two pa sites are located on the headland (Ohumuhumu and Otanenui) and one on the central ridge (Taumarumaru).

Rangikapiti Pā provides panoramic views over the Mangōnui Harbour. It is a significant site to Ngati Kahu, and the terraces and defensive ditch around the pa make it a distinctive feature on the landscape.
