Horowhenua District

Horowhenua is a district on the west coast of the North Island of New Zealand.

Unlike many other districts, it has a distinct identity, so much so that "The Horowhenua", as it is usually called, is regarded more as distinct region than as part of the region of Manawatu-Wanganui, which is how it is officially designated.

Located north of Wellington and Kapiti, the district stretches from slightly north of the town of Otaki in the south to just south of Himatangi in the north, and from the coast to the summit of the Tararua Ranges.

The main town and seat of the district council is Levin, and other towns in the district include Foxton, Shannon, and Tokomaru. The population of the district was 29,868 at the 2006 census.

Much of the area was once an extensive wetland and the centre of a substantial flax industry. It has been progressively drained and converted to productive but flood-prone farmland, with a mixture of loam and peat based soils. Some parts of the wetland, particularly those around Lake Horowhenua are being returned to their former state as a conservation area, with the help of local Māori.

Foxton is of historical note as the main town in Manawatu in the early years of European colonisation, and the centre of a large flax industry. Horticulture and dairying are now the main forms of primary industry in the district, and secondary industries in Horowhenua include manufacturing (especially clothing manufacture) and food processing.

Artesian water

Much use is made of artesian water supplies. The northern part of the district, around Opiki, is situated above a series of aquifers. These are vertically separated from each other by layers of less permeable material, known as aquicludes. Within each aquifer, there may also be pockets of less permeable material, known as "lenses". In descending order, the aquifers below the Opiki district are the Foxton, the Himatangi, and the Opiki Aquifers. Over its whole extent, which is much wider than the Opiki area, the Foxton Aquifer lies mostly between 30 m and 60 m below ground level. Around Opiki it is shallower, generally between 24 m and 35 m below ground.

Although not unique, the Foxton Aquifer in this area has the relatively uncommon quality of being under pressure so that when a bore is tapped into it, the water rises under its own pressure and will flow above ground; i.e. there is flowing artesian water. The head varies with ground level but can be as high as about 2.5 m above ground level. The level to which it will rise defines the potentiometric surface. For obvious reasons, the farmers and residential users who have bores tapping into the Foxton Aquifer regard this as a most useful attribute. In many cases it can avoid the necessity of pumping water from the bore and, for those even more fortunate, it can avoid the necessity of reticulating the water around farm properties by pumping systems. There are natural seasonal fluctuations in levels and pressures, but there is evidence that, even in times of extended dry periods, no property in the area loses positive pressure entirely, although some decline to a critical point. As an aside to that point, it is inevitable that the existing bores in the area will have reduced the potentiometric surface from its original level, and that future permitted bores will continue that trend. There must come a time when those properties which now become critical at those times will lose flowing artesian water.
