Waiariki Institute of Technology (Māori: Whare Takiura o Waiariki) was a tertiary institution based in the city of Rotorua, New Zealand, in the Bay of Plenty region in the central North Island. In May 2016, it merged with Bay of Plenty Polytechnic to form Toi Ohomai Institute of Technology.
Regional campuses existed in Taupō, Tokoroa and Whakatāne, and formerly Tūrangi and Kawerau. These were backed by a variety of specialist campuses and buildings, such as the Waipa Campus just south of Rotorua and the newly established offerings available from Waiariki in the Tauranga suburb of Windermere.
Waiariki was divided into three faculties, which offered masters, graduate, postgraduate and degree qualifications, as well as diplomas and certificates in several subject areas. They were the Faculty of Applied Technology and Primary Industries - Te Kura Takawāo, the Faculty of Business, Information Technology and Creative Arts - Te Kura Taki, and Te Pākaro a Ihenga: Faculty of Health, Education and Humanities.
Qualification subject areas included nursing, teaching, social work, art, sustainability, Māori, forestry, business, computing, tourism and hospitality. These were backed by an equally diverse range of trade-based qualifications, in areas such as engineering, agriculture, horticulture, fashion, carpentry and hairdressing.
