Horotiu

The name, Horotiu, seems to have been used interchangeably with Waikato River, or Pukete. Its first use for the current township seems to occur in 1864, shortly after the invasion of the Waikato.[2] Until then, Horotiu was the name of the upper Waikato river, where its current became faster[3] and of Horotiu pā, on its banks, near Cambridge.[4] An 1858 map only shows the name as Horotiu Plains in the area near the pā.[5] The name, Horotiu, for the Waikato River,[6] upstream from Ngāruawāhia,[7] seems to have remained in use until the 1920s,[8] though the 1859 map named it as Waikato.[5]

Horotiu and Pukete parishes existed from at least 1867,[9] but, until the 1900s, Horotiu was often referred to as Pukete, a name now used for the Hamilton suburb 6 km (3.7 mi) upstream. The railway station changed its name on 23 June 1907,[10] when the proposed post office was referred to as Horotiu (Pukete),[11] and the name of the school was changed from Pukete to Horotiu in 1911.[12] The post office closed in 1988.[13]

Horotiu had a population of 624 at the 2018 New Zealand census, an increase of 126 people (25.3%) since the 2013 census, and an increase of 111 people (21.6%) since the 2006 census. There were 198 households. There were 324 males and 300 females, giving a sex ratio of 1.08 males per female. The median age was 34.8 years, with 150 people (24.0%) aged under 15 years, 114 (18.3%) aged 15 to 29, 306 (49.0%) aged 30 to 64, and 54 (8.7%) aged 65 or older.

Ethnicities were 78.4% European/Pākehā, 34.1% Māori, 3.8% Pacific peoples, 6.2% Asian, and 1.9% other ethnicities (totals add to more than 100% since people could identify with multiple ethnicities).

The proportion of people born overseas was 8.2%, compared with 27.1% nationally.

Although some people objected to giving their religion, 64.9% had no religion, 23.1% were Christian, 1.4% were Buddhist and 1.9% had other religions.

Of those at least 15 years old, 66 (13.9%) people had a bachelor or higher degree, and 108 (22.8%) people had no formal qualifications. The median income was $40,900. The employment status of those at least 15 was that 291 (61.4%) people were employed full-time, 51 (10.8%) were part-time, and 9 (1.9%) were unemployed.[14]

In 2018 the census unit was reduced to about half its previous area, losing most to the west of the railway to Te Kowhai area unit.[15][16] Growth to 1,390 is planned by 2040.[17]

1:250,000

Taupo Pumice Alluvium (Q1a) was deposited on the Hinuera Formation (Q2a) until about 15,000 years ago. Some of the alluvium has been dug for sand and gravel. The Hinuera formation is also sand and gravel, interbedded with silt and some peat.[18] In the last 14,000 years the Waikato River has cut into these formations, forming a low terrace and then cutting deeper.[19]

The low ridge between the Waikato and Waipa rivers is made of Walton Subgroup (eQa – pumiceous fine-grained sand and silt with interbedded peat, pumiceous gravelly sand, diatomaceous mud, and non-welded ignimbrite and tephra), covered in places by Piako Subgroup (1Qa – Late Pleistocene, mainly locally derived, stream and coastal alluvium, and minor fans, with up to 20 m (66 ft) of unconsolidated to very soft, thinly to thickly bedded, yellow-grey to orange-brown, pumiceous mud, silt, sandy mud and gravel, with muddy peat in some valleys).[19]

AFFCO opening year

Ngāti Hauā had a pā named Horotiu near Cambridge[20] and they also had land in this area.[21] The 1858 census put the Ngāti Hauā population at 1,399.[22] By then they had seeded this area with European grasses.[2] Their land was confiscated in 1864.[6]

Horotiu School is a co-educational state primary school covering years 1 to 8[23] with a roll of 233 as of March 2020.[24] The 2012 report on the school said, "the vast majority of students are achieving at or above National Standards" and noted it was in a Decile 3 area.[25] The school dates back to 1879,[26] following a government grant of the land in 1878.[27]

Horotiu also has a playcentre.[28]

Auckland Farmers Cooperative (later Allied Farmers – AFFCO)[29] bought 80 acres (32 ha) in 1914[29] and a riverside gravel pit in 1915.[30] Horotiu Freezing Works opened on 17 January 1916.[31] Horotiu still has AFFCO’s head office[32] and its largest beef processing plant.[33] The parent company, Talley's, opened a Waikato Dairy Co dried milk plant on the same site in August 2018.[34][35] The area has long been associated with dairying, a casein factory having opened in 1919.[36] AFFCO has long been involved with strikes[37] and pollution.[38][39]

2005 Horotiu landfill

Northgate business park, between Horotiu and Te Rapa, covers 109 ha (270 acres)[28] and opened in 2013.[40] Ports of Auckland have 33ha in Northgate for a freight hub.[41]

By 1904 the area was recognised as a source of gravel[42] and pits were established by 1907,[43] especially on the east bank,[44] and continue to produce aggregates and take in clean fill.[45] Other landfilling ended in 2006, when a 1999 consent[18] for a Hamilton City Council landfill expired. It had been started in October 1985 on a 95 ha (230 acres) sand pit (worked from about 1970 to 2000) and was replaced by Hampton Downs. It was closed earlier than originally planned, due to leachate problems.[46] The 1999 consent required use of a vacuum to extract gas from the bores and leachate.[18] Therefore, from November 2004 until 2012, when the emissions declined, methane from the landfill ran a 900kWe Waukesha VHP5904LTD Enginator gas engine generator set.[47]

1921 bridge in 1963

The Horotiu-Pukete section of Te Awa River Ride opened in 2013[48] and an extension to Ngāruawāhia opened on 2 November 2017.[49]

2001 bridge in 2014

Near Horotiu the Waikato is bridged by 2 roads and Te Awa cycleway.

The next bridge upstream is Pukete sewer bridge and downstream, Ngāruawāhia road bridge.

1921 Horotiu Bridge Rd

Construction started about 1920 of a reinforced concrete bridge, with a 25 ft (7.6 m) high arch, a main span of 126 ft (38 m), plus six approach spans of 24 ft (7.3 m), carrying a 16 ft (4.9 m) wide road. It was designed by Toogood and Jones, of Auckland, for £7900, paid by Waikato and Waipa County Councils,[50] though government contributed £1,728.[51][52] The bridge was completed in 1921,[53] though the approaches took longer.[54]

2013 Te Rehu O Waikato Bridge in 2014

2013 Waikato Expressway bridge

The need for the 2001 bridge was reduced by the 142 m (466 ft) long 2013 Waikato Expressway Te Rehu O Waikato Bridge, built 400 m (1,300 ft) upstream. As part of the $200m road section,[57] it used 800 tonnes of steel, including 56 tonne girders, resting on 4 x 'V'-shaped piers,[58] which allowed the main span to be reduced about 20m to 55 m (180 ft).[59] Concrete pre-cast panels were added to them to carry the concrete deck and barriers.[58]

2017 cycleway

The Te Awa cycle bridge is a 140m long, 2.5m wide,[62] $1.3m cable network arch bridge,[63] opened on Thursday 2 November 2017.[49] The bridge is lit from a 9kWh battery, powered by 2 x 100 watt wind turbines and 2 x 250 watt solar panels on 7-metre high masts at the base of the bridge.[64] Since opening the average weekly use by cyclists rose from 133 to 711 and by walkers from 348 to 391.[65]
