Ōhāriu, previously spelled Ohariu and then Ōhariu, is a New Zealand parliamentary electorate returning one Member of Parliament to the House of Representatives.

Through its existence Ohariu-Belmont was represented by Peter Dunne, leader of the United Future party.

Together with a northward shift of New Zealand's population, this resulted in five new electorates having to be created in the upper part of the North Island.

The new electorate contained the section of Wellington City between Crofton Downs and southern Tawa, including Ngaio, Khandallah, Johnsonville and Newlands.

The rest of the electorate consisted of Lower Hutt's hill suburbs of Korokoro, Maungaraki and Normandale.

[5] Despite Dunne having a 7,702 vote majority in Ohariu-Belmont at the 2005 election,[6] United Future's performance was less impressive.

[7] Historically Ohariu (without macrons) was an electorate based around north and western Wellington, contested between 1978 and 1990.

A substantial redrawing of Wellington's boundaries ahead of the final first-past-the-post election in 1993 led to Ohariu being divided between Wellington-Karori and the new electorate of Onslow.

Dunne, then a member of the Labour Party, was the MP for the old Ohariu between 1984 until its abolition, and won Onslow in 1993.
