Henare Wiremu Taratoa (c1830 to 1864) lived in tumultuous times when Maori adopted European lifestyle skills, language, and religion. Educated by missionaries, Taratoa became a teacher and author of a book on the teaching of arithmetic. He travelled to the Pacific Island with Bishop Selwyn where he taught at the Loyalty Islands before becoming a teacher at Octavius Hadfield's school at Otaki. When the Land Wars erupted, Taratoa returned to his home at Tauranga where he set up schools and a Maori council that sought to make peace with the occupying British Forces. War was inevitable. Taratoa fought at the Battles of Gate Pa and Te Ranga where he was killed. When burying the Maori warriors in the trenches, the British soldiers discovered a document on Taratoa that listed the prayers for the day and the rules for war. The rules were similar to the Geneva Conventions drawn up by the Red Cross later that year. The British soldiers donated money to Bishop Selwyn for stained glass windows in a chapel at Lichfield Cathedral England as a memorial to Taratoa and other chivalrous Maori warriors who died defending their country. This biography illustrates a painful period in New Zealand history when Maori, attracted to the European way of life, were compromised by those whom they trusted.
