The Ngati Maru–Ngati Tuwharetoa War (–1832) was one of the conflicts between Māori tribes during the Musket Wars in New Zealand.

In the course of the conflict, the Ngāti Maru iwi invaded the rohe of Ngāti Tūwharetoa on four occasions. The first attack took place at some point after 1822, when a Ngāti Maru war party returning from the Cook Strait suddenly attacked Ngāti Tūwharetoa territories on the southeastern side of Lake Taupō. Under the leadership of Mananui Te Heuheu Tūkino II, Tūwharetoa pursued and destroyed this force. In revenge, Tuterangianini of Ngāti Maru led a successful invasion in late 1827 or early 1828, destroying several settlements. In December 1828, he attacked again, along with Ngāti Raukawa, and destroyed Motu-o-puhi pā. A final attack in January 1831, led by Ngāti Maru's paramount chief, Te Arakai, destroyed Piripekapeka, but was severely defeated by Te Heuheu in a battle at Pareaka. After this, peace was made.

The war had a transformative effect on Ngāti Tūwharetoa, leading them to make greater contact with European traders in order to acquire muskets and strengthening the position of paramount chief, hitherto a form of first among equals, into a strong, hereditary office.

Background

In the early 19th century, northern Māori began to acquire European muskets from traders, leading to more intense and wide-ranging warfare than previously. In particular, Hongi Hika of Ngāpuhi led raids across the North Island. In turn, other tribes migrated and led raids elsewhere. Ngāti Maru at Hauraki were among the tribes that came under attack. They managed to acquire a few muskets and began to undertake long-distance expeditions of their own.

Ngāti Tūwharetoa had been settled around Lake Taupō since the sixteenth century. Because of their inland location they had little contact with Europeans in the early nineteenth century and had not acquired any muskets. The tribe was split into a number of hapū, which often came into conflict with one another, but they sometimes acknowledged a paramount chief with a limited degree of overarching authority in military matters. In the early nineteenth century, this position was claimed by Herea. When he died around 1820, the position was left vacant, but his son Te Heuheu Tūkino II began to seek the role.

Course of the war Desecration of Te Rangi-tua-mātotoru's grave

Sometime after 1822, three chiefs, Pataua, Te Hau o Taranaki, and Wahineiti led a war party of Ngāti Maru through the Taupō region on their way back from Te Rauparaha and Te Rangihaeata's attack on Kapiti. They visited Te Heuheu at Te Rapa and he lent them a number of canoes, including Whakaterekohukohu, to travel across the lake to Marae-kōwhai.

However, one of the chiefs in the war party had a vendetta with Ngāti Raukawa and convinced the war party to attack Ngāti Rua and Ngāti Hinemihi at Pūkawa, who had connections with Ngāti Raukawa. They desecrated the graves of the chiefs nearby, including those of Taipu and Takohe. Then they went to Motutaiko Island and desecrated the bones of Te Rangi-tua-mātotoru, who had been paramount chief before Herea. Then they attacked Motutere, stripping the local women naked and abusing them. One of the women at Motutere was Hurihia, Te Heuheu's sister, who escaped wearing only a fishing net to Te Rapa, where she informed her brother of what had happened.

The chiefs of Tūwharetoa gathered at Motutere to discuss how to respond to this attack. Some of them, notably Te Tauri said that no action should be taken, since the war party had violated tapu and were therefore doomed whatever happened. However, Te Heuheu strenuously pushed for Tūwharetoa to take action. Eventually, he got his way and a war party set out in pursuit of Ngāti Maru.

The Ngāti Maru force had made it to Omaunu on Rangatira Point at the northeastern corner of Lake Taupō, near the modern town of Taupō. The people of Omaunu had been forewarned of the force's bad intentions by Hape, a chieftain of the war party who was himself a member of Ngāti Raukawa and had defected after seeing the war party's behaviour at Pūkawa. The rangatira of Omaunu, Te Poihipi, greeted the war party as guests, advising them to tie up their canoes firmly and to camp outside the walls of the village, well aware that the war party was probably planning to attack them.

Overnight, Te Heuheu's war party made it to Omaunu and surrounded the Ngāti Maru. They attacked at dawn. In the fierce fighting that followed, Pataua, Te Hau o Taranaki, and Wahineiti were all killed. Hape fled to Maungatautari.

First attack on Whakatara In late 1827, Tuterangianini led a large Ngāti Maru war party against Tūwharetoa. One motivation for the attack was getting vengeance (utu) for the deaths of Pataua, Te Hau o Taranaki, and Wahineiti. They may also have been probing the region to see whether they could wipe out Tūwharetoa and settle on their lands. However, the immediate cause was a request from Korokaihuhu, a rangatira of Tuhoe and Ngāti Warahoe, who wanted revenge for Tūwharetoa's massacre of Ngāti Warahoe after the Battle of Kohikete at the end of the Tūhoe–Ngāti Tūwharetoa War in the late eighteenth century. Korokaihuhu travelled to Ngāti Maru and successfully persuaded them to launch an expedition. The expedition had a single musket, which gave them a substantial advantage over Tūwharetoa, who had no such weapons.

The war party first attacked a fortress shared by Tūwharetoa and Ngāti Tahu in the Ātiamuri-Orakei Korako region. Moving south, they were confronted by Te Heuheu II at Pūkawa, but they were victorious. Te Heuheu was almost captured. From there, they continued south and destroyed the fortress of Whakatara Pā near the modern Waihi Village. After this, the war party returned to Hauraki.

Fall of Motu-o-puhi

In December 1828, Tuterangianini led another war party from Ngāti Maru to attack Ngāti Tūwharetoa. The success of the previous expedition led them to believe that they had a good chance of seizing territory and settling permanently. Tuterangianini joined up with a force of Ngāti Raukawa led by Te Ruamaioro, who were migrating towards the southern part of the North Island as a result of pressure from their neighbours. The expedition brought a single musket, the first gun to be brought into the Taupō region.

At Waihāhā, the expedition met the local hapū, Ngāti Te Kohera, who were related to Ngāti Raukawa. They guided the expedition to Pūkawa and then Ngāti Maru went on to Te Rapa, while Ngāti Raukawa took an inland route further to the west. Te Rapa was Te Heuheu's main base, but at this time it was empty because he had gathered all the southern and western Tūwharetoa at Waitahanui to the east to keep them safe from war parties. Therefore, Tuterangianini was able to occupy Te Rapa.

Te Heuheu led his men out to Te Rapa and the two forces presented themselves to one another and performed many haka. Finally, the Ngāti Maru force announced that it was on its way south and posed no threat to Tūwharetoa. To secure their passage through Tūwharetoa territory, Ngāti Maru agreed to hand over a number of women as hostages. Most of these hostages were female relatives of Te Whatanui, one of the Ngāti Maru rangatira: his daughter Te Rangingangana, his niece Rangipoutahi, and his wife Rauoterangi. Two other chieftainesses of Ngāti Maru, Hapai and Pito, were also handed over.

The Ngāti Maru expedition then continued south over the Poutu saddle to Lake Rotoaira, where they rendezvoused with the Ngāti Raukawa force on the western shore at Kotukutuku. The local rangatira, Te Wharerangi, was based at Motu-o-puhi, a fortified village on an island at the northeastern end of Lake Rotoaira. It was home to the Tūwharetoa hapū of Ngāti Hikairo ki Tongariro, Ngāti Waewae, Ngāti Wi, and Ngāti Tama. Since they were now safely out of Te Heuheu's immediate domain, Ngāti Maru decided to attack Motu-o-puhi in order to get revenge for the earlier deaths of members of Ngāti Maru. Ngāti Raukawa agreed to join the attack, because Te Wharerangi had killed some of their chiefs when they were fleeing from a defeat at Mangatoa on the Manawatū River in 1821.

Ngāti Maru made an alliance with the local people of the western shore of the lake, sealed by the marriage of the local woman, Hinehoro, to Te Awhi of Ngāti Maru. They then secretly gathered as many canoes as they could. According to the descendants of Te Wharerangi, the canoes were secretly delivered by one of the local rangatira, Te Huiatahi, who belonged to the Ngāti Waewae hapū of Tūwharetoa and was hostile to Te Wharerangi. Ngāti Waewae tradition strongly denies this. Some descendants of Te Wharerangi also claim that Te Heuheu had told Ngāti Maru about the weaknesses of Motu-o-puhi's fortifications, because Te Wharerangi had refused to let Te Heuheu marry his daughter.. This claim was presented to the Tribunal in 2006 by Tiaho Pillot Once Ngāti Maru had enough canoes, they set out at dawn, attacked Motu-o-puhi from the water, and easily seized the village, thanks especially to their gun. Ngāti Maru lost two chiefs, Te kauauau and Taitanguru, while Pahupahu was killed on the Motu-o-puhi side. Many of the inhabitants of Motu-o-puhi were killed, but Te Wharerangi's brother Hokopakeke Te Huri managed to get many of the women and children, including Te Wharerangi's wife, Te Rangikoaea, his young son, Matuāhu Nini, and his daughter Te Māri, to the Manganuioteao River, where their Ngāti Uenuku relatives lived.

The captured chieftains were lined up and executed one by one with a greenstone patu. As it came to his turn, Te Wharerangi attempted to escape, leaping off a nearby clifftop into the lake, but he was caught and killed by some of the Ngāti Maru who were in canoes nearby. Another chieftain, Hikopo tried the same thing and was also killed, but his body was only found later by Te Heuheu, washed up on the shore, with the treasured pounamu pendant, Kaukaumatua, still around his neck.

Two scouts from Ngāti Te Aho sent out by Te Heuheu saw the burning of Motu-o-puhiand quickly reported the attack to Te Heuheu. With a war-party of Ngāti Te Aho, Ngāti Hinewai, and Ngāti Turumakina, Te Heuheu rushed to Lake Rotoaira. Te Heuheu's brother Iwikau called for an immediate attack, but Te Heuheu refused, because of his regard for Te Whatanui. He also refused to execute the hostages, even though this had been demanded by a number of prominent chiefs: Te Puhi, Paewhenua, Te Rangikaiamokura, Te Rangimonehunehu, and Tauteka. He argued that the female hostages were insufficiently important for their deaths to compensate for the murder of Te Wharerangi. Therefore, Te Heuheu returned home without doing anything.

After the fall of Motu-o-puhi, most of Ngāti Raukawa continued their journey south under Te Ruamaioro. When they reached Onepoto, on the Whanganui River, they were attacked by Pēhi Turoa, one of Te Wharerangi's relatives. They were defeated, retreated to Makatoke, and were defeated again. Te Ruamaioro was killed, while Tupaea, Te Puke, Te Ao, and Wharemakotea were taken prisoner.

Meanwhile, the Ngāti Maru force turned back towards Hauraki, accompanied by the section of Ngāti Raukawa led by Te Whatanui. They were confronted by a war party led by Iwikau at Te Rae, who informed Te Whatanui that his female relatives had not been killed. They continued by canoe to Whareroa, where a large war party under Te Heuheu appeared on the shore. Instead of attacking, Te Heuheu agreed to return the hostages to Te Whatanui, in exchange for Te Rangikoaea, the wife of Te Wharerangi, who had been captured at Motu-o-puhi. Te Heuheu's generosity on this occasion formed the basis of an alliance with Te Whatanui, which continued for the rest of their lives. Then Ngāti Maru returned home.

Second attack on Whakatara
