chunk: There, they find a former quarter-master of the Britannia, Ayrton, who proposes to lead them to the site of the wreckage. However, Ayrton is a traitor, who was not present during the loss of the Britannia, but was abandoned in Australia after a failed attempt to seize control of the ship to practice piracy. He tries to take control of the Duncan, but by sheer luck, this attempt also fails. However the Glenarvans, the Grant children, Paganel and some sailors are left in Australia, and mistakenly believing that the Duncan is lost, they sail to Auckland, New Zealand, from where they want to come back to Europe. When their ship is wrecked south of Auckland on the New Zealand coast, they are captured by a Māori tribe, but luckily manage to escape and board a ship that they discover, to their astonishment, to be the Duncan.
