Karapiro

In about 1600, Te Ihingarangi built a pā (fortified village) called Te Tiki o Ihingarangi near where Lake Karapiro is today.[1]

In 1830 Ngāti Hauā defeated Ngāti Maru in a battle at Taumatawīwī, two kilometres south of Karapiro Domain. On the orders of the Ngāti Hauā chief Te Waharoa, his dead warriors were cremated, this taking place on rocks beside the Waikato River, the location then becoming known as Karāpiro, from the Māori language words karā, meaning "basaltic stone", and piro, meaning "foul smelling". The site was flooded when the dam was built and the lake created in 1947.[2]

A man opened fire inside the Karapiro Cafe and Grits in April 2019.[3] The suspect was later put under mental health care;[4] the victim survived with serious injuries.[5]

The statistical area of Karapiro, which at 191 square kilometres is much larger than the settlement and also includes Te Miro, had a population of 2,334 at the 2018 New Zealand census, an increase of 384 people (19.7%) since the 2013 census, and an increase of 540 people (30.1%) since the 2006 census. There were 810 households. There were 1,185 males and 1,149 females, giving a sex ratio of 1.03 males per female.

Ethnicities were 95.1% European/Pākehā, 8.0% Māori, 1.5% Pacific peoples, 2.8% Asian, and 1.7% other ethnicities (totals add to more than 100% since people could identify with multiple ethnicities).

The proportion of people born overseas was 21.9%, compared with 27.1% nationally.

Although some people objected to giving their religion, 54.1% had no religion, 36.8% were Christian, 0.3% were Hindu, 0.1% were Muslim, 0.4% were Buddhist and 1.8% had other religions.

Of those at least 15 years old, 471 (26.0%) people had a bachelor or higher degree, and 204 (11.3%) people had no formal qualifications. The median income was $44,200, compared with $31,800 nationally. The employment status of those at least 15 was that 1,077 (59.4%) people were employed full-time, 324 (17.9%) were part-time, and 30 (1.7%) were unemployed.[6]

Karapiro settlement is in meshblocks 4005317-8 and 4011907-8, which had a population of 477 people in the 2018 census.[7]

Lake Karapiro is an artificial reservoir lake on the Waikato River, formed in 1947 by damming the Waikato River to store water for the 96-megawatt Karapiro hydroelectric power station.[8]

The lake is regarded as one of New Zealand's best rowing venues. It hosted the World Rowing Championships in 1978 and 2010, as well as the rowing events for the 1950 British Empire Games. Lake Karapiro alternates with the South Island's Lake Ruataniwha in hosting the New Zealand national rowing championships and the New Zealand secondary school rowing championships (Maadi Cup).In March 2006, an International Rowing Federation inspection panel described Karapiro as one of the fairest and most picturesque courses in the world.[9]

The 96-megawatt Karapiro Power Station is located adjacent to the dam at the head of the lake, and is the eighth and last hydroelectric power station located on the Waikato River. Water for the power station up to 362 cubic metres per second (12,800 cu ft/s) at full power, is taken from the lake and passed through three Kaplan turbines in the powerhouse, before being deposited into the lower Waikato River. Each turbine turns a 32 MW generator, and the electricity from the generators is fed into Transpower's national transmission grid. The station is a base load generator due to its need to maintain water flows into the Waikato River system beyond the lake.

The ten-megawatt Horahora Power Station at Horahora, 13 km upstream of Karapiro Dam, part of an earlier hydroelectric power scheme, was flooded with the formation of Lake Karapiro.[10]

Karapiro School is a co-educational state primary school for Year 1 to 6 students,[11][12] with a roll of 25 as of March 2020.[13]
