Located in the eastern Manawatū Plains, the city is near the north bank of the Manawatū River, 35 km (22 mi) from the river's mouth, and 12 km (7 mi) from the end of the Manawatū Gorge, about 140 km (87 mi) north of the capital, Wellington. Palmerston North is the country's eighth-largest urban area, with an urban population of 81,200 (June 2025). The estimated population of Palmerston North city is 90,500 (June 2025).

The official limits of the city take in rural areas to the south, north-east, north-west and west of the main urban area, extending to the Tararua Ranges; including the town of Ashhurst at the mouth of the Manawatū Gorge, the villages of Bunnythorpe and Longburn in the north and west respectively.

Horowhenua District is a territorial authority district on the west coast of the North Island of New Zealand, administered by Horowhenua District Council. Located north of Wellington and Kāpiti, it stretches from slightly north of the town of Ōtaki in the south to just south of Himatangi in the north, and from the coast to the top of the Tararua Range. It is in the Manawatū-Whanganui local government region. The name Horowhenua is Māori for landslide.

Levin is the main town and the seat of the district council. Other towns include Foxton, Shannon and Tokomaru. The population of the district is 38,400 (June 2025).

The Kāpiti Coast District (officially the Kapiti Coast District) is a local government district of the Wellington Region in the lower North Island of New Zealand, 50 km (31 mi) north of Wellington City. The district is named after Kapiti Island, a prominent island 5 kilometres (3.1 mi) offshore.

The population of the district is concentrated in a chain of coastal settlements along State Highway One: Ōtaki, Te Horo, Waikanae, Paraparaumu, Raumati Beach, Raumati South, and Paekākāriki. Paraparaumu is the most populous of these towns and the commercial and administrative centre. Much of the rural land is given over to horticulture; market gardens are common along the highway between the settlements. The area available for agriculture and settlement is narrow and coastal. Much of the eastern part of the district is within the Tararua Forest Park, which covers the rugged Tararua Range, with peaks rising to over 1,500 m (4,900 ft).
