 On 5 March 1826 the ships, "Lambton" and "Rosanna", reached Stewart Island, which Herd explored and then dismissed as a possible settlement, before sailing north to inspect land around Otago Harbour.Herd was unconvinced that area was the ideal location and sailed instead for Te Whanganui-a-Tara, (present-day Wellington Harbour), which Herd named Lambton Harbour.Herd explored the area and identified land at the south-west of the harbour as the best place for a European settlement, ignoring the presence of a large pā that was home to members of Te Āti Awa tribe.
