Cameron and the British troops were sent to New Zealand at the request of the Governor, Sir George Grey. The new colony was severely short of land in which to expand, most of the best land in the North Island was owned and occupied by the Maori. They had recently formed a political alliance called the King Movement to resist the further sale of Maori land to the Pakeha government. The main base for the King Movement was the Waikato, a rich and fertile region immediately south of Auckland which was then the capital of New Zealand. Furthrmore the Maori had the temerity to insist on their independence from the Colonial Governmnet, an independence that was guaranteed to them by the Treaty of Waitangi twenty years earlier.
Governor Grey was determined to occupy and confiscate the Maori land of the Waikato and to do this he needed large numbers of British Troops. He presented a case to the Colonial Office in London which greatly exaggerated the threats and dangers of the Independent Maori Movement, claiming that the European settlement was in danger of being wiped out. To meet the supposed danger the British Government sent out fourteen thousand tropps commanded by Major Gneral Duncan Cameron.
Cameron arrived in New Zealand early in 1863 and the Invasion of the Waikato began in July 1863. However after a very short advance Cameron realised that his supply lines were severely threatened by the enemy. Three months were spent in securing his rear from guerilla attack. However this was not to the liking of the New Zealand Government who saw the delay as unnecessary and even cowardly. Relations between Grey and Cameron began to detiorate from this point on and as they did so Grey was faced with more and more critcism from the new Zealand Press and public.
Cameron conducted a careful and clever campaign agains the Waikato Maori seeking always to minimize the casualties of both his own men and the enemy. One historian at least believes that Cameron deliberately allowed the besieged and surrounded Maori at Orakau to escape. This of course did not please the New Zealand public who wanted the Maori to be punished for their intransigence.
Eventually the Maori retreated into what is now called The King Country, south of Te Awamutu and the British Forces apparantly decided they had conquered enough land for a government that was not too grateful and the Waikato War petered out.
Meanwhile there was conflict in the Bay of Plenty around Tauranga. It was here that Cameron made his most serious tactical blunder of the New Zealand Wars when he authorized the attack on Gate Pa and suffered a very heavy loss. It seems likely that he had overestimated the effectiveness of the very heavy bombardement of the Pa and anticipated little resistance from the defenders.
As the Tauranga Campaign wound down fighting flared up in Taranaki. Cameron saw this conflict as completely unnecessary being wholly provoked by the rapacious confiscation of Maori Land. Although he could not refuse orders to involve the British Troops he conducted the campign at a snail's pace and eventuallu stopped advancing altogether. By now relations between Cameron and Grey were very frosty.
Cameron wrote to the Colonial Office and recommended that all British Troops should be withdrawn from New Zealand. At the same time he submitted his resignation as commander of the troops. Although the British Troops were not immediately withdrawn from New Zealand they took a very minor role in the subsequent conflicts.
Cameron returned to Britain but not in disgrace. On arriving in England he was given a knighthood, made a full General and appointed Governor of the Royal Military College at Sandhurst.
