After three months' sailing, the group landed in New Zealand. The Sardon brothers had only a brief life in the mission. The elder brother, who had been a barrister before becoming a priest, died of pneumonia; the young brother, some time later, was shipwrecked on the New Zealand coast. Bucas was assigned to the
Waikato. Bishop Pompallier supplied him with some provisions for the journey to Waikato, including a double-barrel gun and £4 in cash. Bucas travelled to Waikato accompanied by Māori guides. Bucas worked as a missionary among the Māori until their
insurrection against the British Government. During those years, Bucas had grown to respect the Māori, had learned their language, and was deeply interested in their welfare, both spiritual and practical. The Māori respected him in return. However, the strong relationship between Bucas and the Māori led to the end of his missionary service among the Māori. One day in a secluded location, Bucas accidentally came upon a group of Maoris practising military drills in preparation to fight the British. Seeing they were awkward when using rifles, his military experience prompted him to drill them in the correct use of the rifles. Bucas had not considered the consequences of doing this, but when the British military authorities heard about it, they told Bishop Pompallier that Bucas must be removed from New Zealand. Bucas was taken on board the English Admiral's flagship (where he was treated with courtesy) and taken to
Melbourne, Australia. == Brisbane ==
