As a Tohunga o Tumatauenga he was acknowledged by the Ngāpuhi of the Bay of Islands as a spiritual leader who possessed the ability of communicating between the spiritual and temporal realms through karakia, pātere or performing waiata. On 28 November 1832, the Revd. Alfred Brown witnessed Tohitapu practicing as a Tohunga to foresee the success of Tītore’s second muru to Tauranga, which followed the Girls' War in the Bay of Islands.
The gate incident
Tohitapu lived at Te Haumi and was a frequent visitor to the Revd. Henry Williams at Paihia. Although there occurred miss-understandings and several confrontations between them. One of the most severe was the confrontation on 12 January 1824, which was witnessed by other chiefs. The incident began when Tohitapu visited the mission. As the gate was shut, Tohitapu jumped over the fence. Williams demanded that Tohitapu enter the mission using the gate. Tohitapu was a chief and a tohunga, skilled in the magic known as makutu. Tohitapu was offended by William's demand and began a threatening haka flourishing his mere and taiaha. Williams faced down this challenge. Tohitapu then seized a pot, which he claimed as compensation for hurting his foot in jumping over the fence, whereupon Williams seized the pot from Tohitapu. The incidence continued through the night during which Tohitapu began a karakia or incantation of bewitchment. Williams had no fear of the karakia. The next morning Tohitapu and Williams reconciled their differences, although the failure of the karakia to have any effect on Henry Williams reinforced his mana and created doubt among the Ngāpuhi as to the powers of a Tohunga. Tohitapu remained a supporter of Williams and the mission at Paihia. In 1829, Tohitapu came to the assistance of the CMS missionaries when the action of one of the Māori assistants of the mission damaged part of one of Te Koki’s houses, which was an serious offence against Māori custom. Te Koki was the principal chief of the Ngāpuhi at Paihia, uncle of Hongi Hika, brother to Tuhikura, of Ngāti Rehua, and husband of Ana Hamu. Tohitapu accepted changes that followed from the work of the CMS missionaries. In March 1828, Tohitapu, Henry Williams and George Clarke were present at fighting occurring between the Ngāpuhi and Te Mahurehure hapu. Tohitapu addressed the Ngāpuhi and ordered that no fighting would take place the next day as it was a Sunday. The Revd A. N. Brown reported in his journal of August 1831 that Tohitapu choose to apply a less severe punishment to a slave, when the penalty under Māori custom was usually death.
As a mediator
Tohitapu also engaged in mediation of conflicts between Ngāpuhi chiefs. The death of Tiki, a son of Pōmare I and the subsequent death of Te Whareumu in 1828 threw the Hokianga into a state of uncertainty as the Ngāpuhi chiefs debated whether revenge was necessary following the death of a chief. Henry Williams, Richard Davis and Tohitapu mediated between the combatants. As the chiefs did not want to escalate the fighting, a peaceful resolution was achieved. During the Girls' War in March 1830, Tohitapu sounght the assistance of the CMS missionaries to mediated between the combatants. In December 1831, Tohitapu requested that the CMS missionaries intervene to stop the fighting at Kororāreka between the warriors of Tītore and Tareha.
Tohitapu
The journals of the Church Missionary Society missionaries describe Tohitapu as a person of high intelligence and considerable mana among the Te Roroa and Ngāpuhi. The Revd. Henry Williams said “he is a very important person in his way, though our good folks generally cannot manage him”. Tohitapu did not renounce his status as a Tohunga and warrior or become a Christian. From January 1832 until late July 1832 Tohitapu was part of the muru, or war expedition, that Tītore and Ngāpuhi warriors made to Tauranga, which followed the Girls' War. In February 1833, Tohitapu joined the second muru led by Tītore with Te Rarawa warriors, allies of the Ngāpuhi, from the North Cape back to Tauranga to continue the war expedition. Henry Williams accompanied both expeditions in an attempt to bring them to a peaceful conclusion. Tohitapu died in the Bay of Islands on 14 July 1833. On 17 January 1834, CMS missionaries went to Wangai, a settlement south-east of Paihia, to attend the funeral feast held at the hahunga of the bones of Tohitapu.
