On 30 December Pompallier, Fr Louis Catherin Servant SM and Brother Michel (Antoine) Colombon sailed for the
Hokianga and arrived at the home of
Thomas and Mary Poynton on 10 January 1838. It was to be his headquarters and the chief scene of his labour for the next 30 years. Pompallier celebrated the first Traditional Latin
Mass in New Zealand at Totara Point on 13 January 1838. He immediately set about establishing Catholic mission stations. He quickly learned both English and Māori. Bishop Pompallier travelled extensively by schooner around both North and South Islands, setting up mission stations. Marist reinforcements arrived on the
Reine de Paix on 18 June 1839 (Fathers Baty, and Petit and Brothers Elie Regis, Augustin and Florentin). On 8 December, four more Marists arrived. They were Fathers
Philippe Viard, Petit-Jean, Comte and Chevron and Brother Attale. Pompallier was present at Waitangi on the day before and the morning of the signing of the
Treaty of Waitangi, which was held across the bay from Kororareka, on 6 February 1840. Pompallier pushed for a guaranteed freedom of religion. Fifty years later, in his 1890 publication about the Treaty,
William Colenso recorded that Pompellier arrived dressed in full "canonicals" (ceremonial robes) and did not appear at ease. Nevertheless, mainly due to Pompellier's insistence on the matter of religious tolerance,
Henry Williams said to those present "E mea ana te Kawana, ko nga whakapono katoa, o Ingarani, o nga Weteriana, o Roma, me te ritenga Maori hoki, e tiakina ngatahitia e ia." ("The Governor says the several faiths [beliefs] of England, of the Wesleyans, of Rome, and also the Maori custom, shall be alike protected by him."). Pompallier was worried the treaty would hamper his mission and Colenso overheard that he had advised some Catholic Maori chiefs not to sign the treaty. A separate Apostolic Vicariate of New Zealand was erected in 1842. Pompallier then became the Vicar Apostolic of New Zealand. In 1846, with Viard already appointed as his assistant bishop, Pompallier set off to Rome for his
Ad limina visit. ==Conflict and resolution==
