The Battle of Hingakaka was fought between two MÃÂori armies of the North Island near Te Awamutu and à Âhaupà  in the Waikato, probably in about 1807. It was the largest battle ever fought in New Zealand. The attacking army consisted of NgÃÂti Toa, NgÃÂti Raukawa and allied tribes from the west coast south of the Waikato, the southern North Island and the east coast. The defending army consisted of Waikato and NgÃÂti Maniapoto, with support from NgÃÂti WhÃÂtua and Hauraki. The attackers had between 7,000 and 10,000 warriors, greatly outnumbering the defenders with 3,000 warriors, but the defenders, led by Waikato chief Te Rauangaanga, won the battle.
Early historian Percy Smith placed the battle at about 1780, basing the date purely on tribal genealogies, but evidence from Maori oral histories from warriors who fought in the battle and were still alive well after contact with Europeans suggests that 1780 is far too early. The NgÃÂti WhÃÂtua chief Murupaenga, who led his warriors into action in the battle, was judged by Samuel Marsden to be about 50 when he saw him in 1820. A date of 1780 would make him about 10 â far too young to be a leader of warriors. An account by Noka Hukanui said that the battle of Hingakaka occurred just before the battle of Moremonui, which took place two years before the attack on the Boyd in December 1809. Moremonui is therefore dated to 1807 or 1808, and Hingakaka about the same.
The take, or cause, happened about three years before the battle. Pikauterangi, a chief of NgÃÂti Toa from the Marokopa district, was aggrieved over the poor distribution of the kahawai fish harvest, according to Pei Te Hurinui Jones. Other accounts say that Pikauterangi took the biggest fish for himself and he was seized and dunked to the point where he nearly drowned. In vengeance, he killed members of the NgÃÂti Apakura, who were one of the hapu hosting the fish feast, cooked their bodies and distributed them for eating among NgÃÂti Kauwhata and NgÃÂti Raukawa.
Pikauterangi then travelled around the lower North Island collecting a large force from many smaller allied hapà « and iwi. He raised about 4,000 men from the Wellington region and 3,000 from the East Coast tribes of NgÃÂti Porou and NgÃÂti Kahungunu. This was combined with a separate force of Te ÃÂti Awa, NgÃÂti Ruanui and tribes from the Whanganui who had previously fought with NgÃÂti Maniapoto.
In response, NgÃÂti Maniapoto and the Waikato tribes allied with NgÃÂti WhÃÂtua and Hauraki hapà «. The alliance made preparations to establish a series of warning systems stretching from Kakepuku mountain to Mount Taupiri to alert the WaikatoâÂÂManiapoto forces of impending invasion, and a battle strategy to repel and defeat the invading forces of Pikauterangi, and constructed a series of pàpahà « (pàequipped with warning devices):
When alerted by NgÃÂti Maniapoto of impending attack or invasion by external forces the Mangatoatoa pàalarm was sounded, which carried to Waiari pÃÂ, whose alarm was then sounded, and so on to Nukuhau, Maniapoto pÃÂ, and Taupiri, so that all of Waikato heard. On hearing the alarm, WaikatoâÂÂManiapoto would meet at Mangatoatoa as planned.
The attackers assembled at à Âtorohanga to invade the Waipàdistrict. They numbered 7,000 to 10,000 warriors, probably the largest army ever assembled for battle in New Zealand before or since. Invaders were first spotted by Wahanui, a Maniapoto chief, just south of à Âtorohanga. He sent runners to the pàpahà « at Mangatoatoa to raise the alarm and warn the WaikatoâÂÂManiapoto forces of the impending attack.
The day before the battle the two armies drew up before each other. The combined WhÃÂtuaâÂÂHauraki and WaikatoâÂÂManiapoto forces, realising their numbers were far fewer at about 1,600 (some sources say 3,000), arranged bunches of feathers on top of fern to simulate the head feathers of warriors held in reserve, while other chiefs made war-like speeches in the fern to imaginary warriors. Choosing to draw the invading force into ambush, the Waikato defenders chose Te Mangeo ridge line just south of Lake Ngaroto (and west of where the Ngaroto railway station was later).
Te Rauangaanga, the father of Te Wherowhero, placed his army on the high ground at the end of a narrow ridge in three groups. The invading force assembled at the foot of the spur (possibly near where the railway line is now). Huahua's Maniapoto forces attacked with their tactic "Te Kawau Maro" (swoop of the cormorant). They charged down the hill in a flying wedge into the centre of the invading force. The defenders reeled back, allowing the attackers to envelop them. The second group of the defending forces then rushed down the hill to hit the confused army of Pikauterangi in the flank. The turning point came when Pikauterangi was killed by a blow from Te Rauangaanga. In a panic the invaders tried to retreat along a narrow gap between the ridge and the lake but were ambushed by Tiriwa's men who had been waiting in the bush along the ridge. The NgÃÂti Toa were forced into the swamplands along the lake margin; some tried to swim the lake but were killed by patrols waiting on the far side.
Many thousands died in the attack. Pei Jones of Tainui says that 16,000 warriors are said to have taken part. Combatants included WaikatoâÂÂManiapoto, NgÃÂti Toa and NgÃÂti Raukawa. NgÃÂti Raukawa alone are said to have lost 1,600 warriors in battle, including two chiefs. Others came from Taranaki, from Kaipara in Northland, and as far east as Bay of Plenty and Hawke's Bay. The battle is known as Hingakaka, due to the large number of chiefs who died, though the exact pronunciation and meaning of the term is uncertain. One account collected by Jones says that it is Hinga-kÃÂkÃÂ, meaning 'fall of kÃÂkÃÂ' (MÃÂori hunted kÃÂkàfor food). According to an account by George Grey, it is Hënga-kaka, meaning fish 'hauled up in the kind of net called kaka'.
The sacred carving Te Uenuku was lost in the carnage, and not recovered until 1906.
The victorious Tainui warriors considered following up their decisive victory with a campaign against the tribes that had made war on them. However, NgÃÂti WhÃÂtua's tohunga had a dream in which he saw NgÃÂpuhi launching an attack on the Kaipara in their absence, so NgÃÂti WhÃÂtua returned home, where they defeated an attempted invasion by NgÃÂpuhi in the battle of Moremonui. Hikairo of NgÃÂti Apakura wanted to continue the war against NgÃÂti Raukawa, who had retreated to Maungatautari, but Waikato had had enough of fighting for the meantime. NgÃÂti Apakura set out after NgÃÂti Raukawa anyway, but were defeated, with Hikairo being killed.
In 1810 Waikato warriors set out down the west coast on a raid. At Rangikaiwaka on the coast they met a force of NgÃÂti Tama and a NgÃÂti Haua chief, Taiporutu, was killed. As a result of this another WaikatoâÂÂManiapoto war party set out to gain utu to punish NgÃÂti Tama. The avenging warriors were ambushed and defeated by NgÃÂti Tama and their chief Raparapa.
Around 1819âÂÂ20, during the NgÃÂti Toa migration southwards after being evicted from Kawhia by WaikatoâÂÂManiapoto after the Te Arawi battle, Apihai Te Kawau of NgÃÂti WhÃÂtua, Kukutai of NgÃÂti Tipa (Waikato), and Peehi Tukorehu of NgÃÂti Paretekawa (Maniapoto) embarked with some 400âÂÂ500 distinguished warriors on the "Amio Whenua" expedition to seek retribution or utu from the tribes who had sought to invade their ancestral homelands in the Waipa and Waikato territories during the Hingakaka battle. After encircling the land from Waikato and Maungatautari to Te Arawa and Tuhoe, and through the Tai Rawhiti district to Te Mahia, then on to Wairarapa and across to Manawatu and Whanganui, the "ope taua" (war party) was eventually besieged by Te ÃÂti Awa forces at Pukerangiora PÃÂ, on the banks of the Waitara River, Taranaki. A large WaikatoâÂÂManiapoto force under Te Wherowhero, Te Hiakai, Mama, and others was raised to break the siege of Pukerangiora pàand free the "Amio Whenua Ope Taua" (Amio Whenua War Party). On the way, this relieving force passed near Okoki pÃÂ, where they met the NgÃÂti Toa under Te Rauparaha, with many Te ÃÂti Awa warriors. The NgÃÂti Toa and Te ÃÂti Awa were victorious in the battle of Motunui, but nevertheless the relieving force continued on to unite with the Amio Whenua War Party, and then returned without further fighting to their homelands at Waikato and Waipa.
This led to further conflict and was the immediate background to the NgÃÂti Toa forming alliances with NgÃÂti Tama and NgÃÂti Mutunga in the great NgÃÂti Toa upheaval of 1821âÂÂ22. This attack in turn led to further attacks and counterattacks, building to a climax in 1831 when a large Waikato contingent alleged to be about 4,000 warriors carried out a brutal and sustained campaign over several years led by the great Waikato warrior Te Wherowhero. When women and children attempted to flee the Pukerangiora pàthey were killed. When the men emerged in a weakened state many of them jumped over the cliff to avoid the Waikato warriors. The fugitives were tracked down and killed anyway. Te Wherowhero killed 150 prisoners with his favourite greenstone mere, only stopping when his arm got too tired. The NgÃÂti Maniapoto chief Tukorehu showed no mercy to the Pukerangiora people, the same people who had saved his life and his war party 10 years earlier, placing the heads of the pÃÂ's chiefs, Whatitiri and Pekapeka, on poles in front of the wharenui that had housed him a decade before. This act was well known to all the other tribes.
