It is believed that European concepts of farming and horticultural production were introduced
to this area by Korehako, a European who was captured at Aotea harbour, near Kawhia by an
Ngati Koura war party. He was transported inland to Te Rapa Pa (by the Waikato Hospital)
and later lived amongst Ngati Wairere at Kirikiriroa Pa. Early European missionaries recorded
seeing him in this location during the early 1840's, but noted his poor state of mental health.

History tells us that the first peach stone was introduced by a runaway convict captured at Aotea Harbour in the 1830s. His European name was unknown but he was called Korehako by the locals. From this fortuitous beginning, the nectar of the peach spread throughout the Waikato, and the establishment of many peach orchards began. The peach trees brought wealth and fame to the Maori tribes, most notably to Tainui. George (Korihako) Thomas Hanmore Hull was baptized on 1 March 1830 in Christ Church, St Marleybone, Cosway Street, Middlesex, Kensington, ENG.
2 He immigrated to from London to Sydney on the Renown and then to the BOI about 1833.
