Omarumutu is a community in the Ōpōtiki District and Bay of Plenty Region of New Zealand's North Island, located near the mouth of the Waiaua River.

Omarumutu is in an SA1 statistical area, which also includes Waiaua, and covers 14.23 km2 (5.49 sq mi).

Tūtāmure's original fortifications are still visible; the nearby Makeo peak was one of his strongholds.

[7] Omarumutu War Memorial Hall, located on the marae, was opened by Minister of Māori Affairs Ralph Hanan on 18 March 1961.

Pine Taiapa oversaw the creation of the carvings, tukutuku and kōwhaiwhai that decorate the hall.

[8][6] A memorial cenotaph on the marae, a white column on a concrete base and funeral urn, was initially unveiled with the names of eight local men who died during wars.

A granite memorial stone, also on a concrete base, lists the name of a further four men who died during World War II.

[9] In October 2020, the Government committed $61,944 from the Provincial Growth Fund to renovate the war memorial, toilets and cooking shed, creating an estimated 8 jobs.
