Māori/Pākehā relations – peaceful from the time of Cook's visit and through the first sealing boom from 1792–1797 – soured with the theft of a red shirt, a knife and other articles by a chief Te Wahia from the "Sydney Cove" on the Otago Harbour late in 1810 – and by his killing by an angered sealer. From this there ensued the Sealers' War a series of attacks and counter-attacks, carried out by persons who soon lost sight of the original cause. Māori killed four men from the schooner "The Brothers" (massacred at Molyneux Harbour); several sailors from the "General Gates", and three lascars from the brig "Matilda". The feud continued until 1823 when Captain Edwardson succeeded in ending it, thus sparking a new sealing boom desired by both Māori and Pākehā.
