In 1840 more than 500 chiefs from all over New Zealand signed the Treaty of Waitangi with representatives of the Crown. Only one sheet was used in the South Island – the Herald (Bunbury) sheet carried with Major Thomas Bunbury aboard which sailed from the Bay of Islands on 28 April. The Cook Strait (Henry Williams) sheet was used at Arapaoa Island and Rangitoto ki te Tonga / D'Urville Island at the northern end of the South Island, but was not signed by Ngāi Tahu.
