The Diocese of Waikato and Taranaki is one of the thirteen dioceses and hui amorangi (Maori Dioceses) of the Anglican Church in Aotearoa, New Zealand and Polynesia. The diocese covers the area from the Waikato to the area surrounding Mount Taranaki on the north island of New Zealand.
The diocese was established in 1926 as the Diocese of Waikato, with Cecil Arthur Cherrington being the first bishop. In 2010, the name of the diocese was changed to the Diocese of Waikato and Taranaki. This reflects the structure of the diocese (since 2008), with two bishoprics and two co-ordinary (presiding) bishops.
The seat of the Bishop of Waikato is at St Peter's Cathedral in Hamilton. The current Bishop of Waikato is Helen-Ann Hartley.
The seat of the Bishop of Taranaki is at the Taranaki Cathedral Church of St Mary. The incumbent Bishop of Taranaki is Philip Richardson (who has been the archbishop of the New Zealand dioceses since 1 May 2013). Richardson had previously been the only suffragan Bishop in Taranaki in the Waikato diocese from 1999 until the co-diocesan arrangement started in 2008.
