24-535: North-west Nelson Forest Park , also spelled Northwest Nelson Forest Park and North West Nelson Forest Park , is a forest park that was initially very large and managed by the New Zealand Forest Service until the Department of Conservation was formed in 1987. It existed in its initial form from 1970 until 1996, when most of it became Kahurangi National Park . Since then, the remainder of
48-588: A loss during the 1970s, until 1981 when a more optimised, commercially viable method for extracting iron was implemented, leading to an expansion of the Glenbrook facilities. In the Think Big era of New Zealand industrialisation , the mill was upgraded. In 1987, New Zealand Steel was acquired by Equiticorp. Equiticorp was bankrupted in the New Zealand sharemarket crash of 1987 . In 1989 New Zealand Steel
72-439: A slurry and transported to the mill by an 18 kilometre long pipeline . Approximately, 1.2 million tonnes of ironsand ore are delivered to the mill annually. The area is estimated to contain over a billion tonnes. Glenbrook's iron plant contains four multiple hearth furnaces , four rotary kilns , and two melters. The kilns directly reduce the ore to metallic iron. This process is unusual as most mills use blast furnaces for
96-524: Is notable due to its unique utilization of ironsand as its ore . Because ironsand is a low grade ore with many contaminants, the mill's primary plants' operations and equipment are unusual. The west coast beaches of the North Island of New Zealand between Kaipara Harbour and Whanganui contain ironsand deposits rich in the mineral titanomagnetite . From the late 19th century to the 1950s, there were many unsuccessful attempts to smelt steel from
120-706: The Auckland , and Waikato communities. The New Zealand Forest Service was relaunched by the Labour–NZ First Coalition Government as Te Uru Rākau on 11 May 2018. New Zealand Steel New Zealand Steel Limited is the owner of the Glenbrook Steel Mill , a steel mill located 40 kilometres south of Auckland , in Glenbrook, New Zealand . The mill was constructed in 1968 and began producing steel products in 1969. Currently,
144-502: The 1970s, mining companies explored within the forest park and that led to public requests to give the area the higher protection of a national park . The proposal that created most concern was Coronado Global Resources' application to bulldoze a track to the Mount Arthur Tablelands. Much of the forest park plus parts of Mt Owen and Matiri State Forests became Kahurangi National Park in 1996. Around 60 land parcels of
168-514: The Crown (public/government) retained ownership of the land, and sold a licence to fell the trees to a commercially operated forestry company. These forestry companies operated under what is known as Crown Forest Licences. The Crown Forestry Rental Trust works to expedite the settlement of Māori claims against the Crown, which involve or could involve Crown forest licensed lands. Crown licensed forests contain limited recreational access, to reflect
192-421: The Crown entered into a 100-year mining licence with New Zealand Steel to extract iron sand . Trees are cleared before mining can start so a large area of the forest is not planted and is unavailable for public access. Once mining is complete over an area, mine tailings are re-spread and the area replanted. One of the last remaining Crown Forests, Waiuku offers a wide range of free recreational opportunities to
216-681: The Crown's production forests on the West Coast operation passed onto Timberlands West Coast Limited in 1990. In 1987 the NZ Forest Service was disbanded and the New Zealand Government began selling Forest assets. The majority of forests were sold between 1990 and 1992, with the SOE Forestry Corporation of New Zealand sold in 1996. In order to offset against future Waitangi Tribunal Claims
240-743: The NZ Steel Investigating Company under the Iron and Steel Industry Act 1959 as a vehicle for the investigations. New Zealand Steel Limited was incorporated by the New Zealand Government in 1965. In 1967, construction started on a mill at Glenbrook. Glenbrook was chosen as the site due to the area's proximity to the Waikato North Head ironsand mine and Huntly Power Station . Commercial operations began in 1968, with imported feed coil being used to produce steel for domestic and Pacific Island markets. The company pioneered
264-410: The New Zealand Government would provide funding of up to $ 140 million for an initiative to halve the consumption of coal at the Glenbrook plant and reduce carbon emissions. The project involves installation of an electric arc furnace to replace coal as the heat source for recycling scrap metal. The ironsand ore is mined at an opencast mine at Waikato North Head . The ironsand is then mixed to form

#1732794572530288-597: The North-west Nelson Forest Park were excluded from Kahurangi National Park for a variety of reasons. These include hydro stations, grazing leases, sphagnum moss gathering areas, and mining operations or interests. As a result, remaining areas of North-west Nelson Forest Park are highly fragmented. The largest of those excluded parcels is the Taitapu Block, some 28,000 ha (69,000 acres) surrounding Lake Otuhie south of Mangarakau , as it
312-620: The State Forest Service. The State Forest Service changed its name to the New Zealand Forest Service in 1949, at about the same time that the Forests Act of 1949 passed through Parliament. The New Zealand Forest Service was responsible for the management of New Zealand's state-owned forests, including forestry, conservation and recreational functions, and was abolished in 1987. The Ministry of Forestry
336-494: The control of the Licensee (and with the ability for the licensee to charge for use). In practice, the licensed tree harvesting companies frequently breach these contracts, and LINZ does little or nothing to enforce the licence conditions on behalf of the public, nor rectify these breaches. Anyone can obtain a copy of a Crown Forest Licence from LINZ. On each licence, Section 6 sets out the conditions for Public Entry. In 1966,
360-399: The direct reduction process for reducing iron oxide (ironsand) into metallic iron. This culminated in the commissioning in 1970 of iron and steelmaking facilities to produce billets for domestic and export markets. Expansion continued with the commissioning of a pipe plant in 1972 and a prepainting line in 1982. Total output at this time averaged 300,000 tonnes a year. The steel company ran at
384-518: The forest park has been made up of many disparate and unconnected areas around the perimeter of the national park. Beginning in 1920, forest parks were gazetted north of the Buller River . In the end, there were thirteen separate forest parks. The northernmost eight of those parks were gazetted as the North-west Nelson Forest Park in 1970. The North-west Nelson Forest Park covered approximately 360,000 ha (890,000 acres) of land. The forest park
408-449: The historic public access in New Zealand forests and the continued Crown ownership. It is a commonly held belief in New Zealand that all Crown Forests are open to the public for any recreation. The Crown Forest Licences usually only provide for public access for walkers. Recreational access may be provided for through Section 7, Public Access Easements or Appendices which set out "Continuing Recreational Use" for organisations (clubs) within
432-544: The ironsands. A prize offered by the Taranaki Provincial Government was never claimed, mostly due to problems encountered by people attempting to process the iron sand, such as a viscous slag of titanium carbides and nitrides that forms and blocks equipment when heat is applied to the sand. In 1954, the Department of Scientific and Industrial Research began investigating smelting from the ironsands. In 1959, The New Zealand Government established
456-631: The mill produces 650,000 tonnes of steel a year, which is either used domestically or exported. Over 90% of New Zealand's steel requirements are produced at Glenbrook, while the remaining volume is produced by Pacific Steel, a steel recycling facility in Ōtāhuhu , Auckland. The mill is served by the Mission Bush Branch railway line , which was formerly a branch line to Waiuku . Coal and lime trains arrive daily. Steel products are also transported daily. The mill employs 1,150 full-time staff and 200 semi-permanent contractors. New Zealand Steel
480-431: The reduction process. In the steelmaking plant, vanadium recovery and removal is done due to the high vanadium content of the ironsand ore. The sand also contains aluminium , manganese and titanium . Oxidation of the molten metal and contaminants is achieved by a basic oxygen steelmaking facility. The process used in the converter is the second unusual piece of equipment: oxygen is blown on both top and bottom of
504-597: Was acquired by Helenus Corporation, which consisted of Fisher & Paykel , Steel & Tube, ANZ Bank and BHP . In 1992, BHP took up a controlling interest with an 81% shareholding by acquiring the shares of Fisher & Paykel and Steel & Tube. The company was initially renamed BHP New Zealand Steel Limited, then in 2002 was renamed New Zealand Steel when BHP Steel was listed on the Australian Securities Exchange as BlueScope . On 21 May 2023, Prime Minister Chris Hipkins announced that

#1732794572530528-475: Was managed by the New Zealand Forest Service . In 1970, many of the tracks in the park were overgrown. The Forest Service started on a programme of work to promote recreation in the park, including cutting new tracks and building huts. In 1987, the Forest Service was amalgamated with other organisations and became the Department of Conservation , which took over the management of the state forests. From
