The Omata electorate was named after
Omata in Taranaki, a locality just south-west of
New Plymouth. The electorate's boundary was a straight line that started at the coast between Omata and New Plymouth, and it proceeded in a south-east direction to near where
Pātea is located. Population centres located in the electorate included
Ōpunake,
Manaia,
Hāwera, and
Eltham. In the 1870 electoral redistribution, the Omata electorate was abolished. The electorate's area was effectively increased towards the east (the easternmost boundary reached the
Whanganui River), gaining a large area from the
Grey and Bell electorate, and the name changed to after Mount Egmont, the original European name of
Mount Taranaki. ==History==
