Unfortunately, owing doubtless to imperfect geographical knowledge on the part of those responsible, these boundaries were but loosely defined, for if they had been strictly adhered to, then Britain was setting up a claim not only to Cook's valuable discoveries, but to all the islands eastward of Australia, as far as the western coast of South America, embracing many Spanish discoveries; while on the other hand they excluded not only Stewart's Island, but all that part of the Southern Island of New Zealand south of Bank's Peninsula. Governor Philip's Commission was therefore faulty, because it asserted excessive rights in the one direction and made insufficient claims on the other.
It is true that in later years these boundaries were abandoned and the position made even more anomalous. During the Governorship of Sir Thomas Brisbane it was deemed expedient to separate Van Dieman's Land from New South Wales, and more circumscribed limits were assigned to the Mother State. In this readjustment, whether by accident or design it is impossible now to say, not only Van Dieman's Land but New Zealand were excluded from amongst the dependencies of New South Wales. Then it became an arguable point whether the word "adjacent" had ever covered Islands so far distant from the parent colony, and much legal acumen was expended in the effort to justify the contention that New Zealand had always been beyond the pale of the dependencies.
Up to this point, however, the official mind had never been troubled by doubts as to the extent of its jurisdiction. Governor Philip not only believed that his authority extended to New Zealand, but far beyond it, and under this belief he actually colonised Norfolk Island as a part of the territory he had been commissioned to govern. In like manner the British Government believed it had a right to all that it claimed in Philip's Commission; and at the Congress of Vienna at the close of the Napoleonic wars in 1814, when the map of Europe was recast, it had its claims allowed, New Zealand being acknowledged by the Great Powers to be a portion of our then infant Empire. Even earlier in the century Ministers had seriously discussed a representation made by Lieutenant-Colonel Foveaux, of the New South Wales Corps, to appoint a Lieutenant-Governor in New Zealand, which under his scheme was to become a penal settlement subordinate to New South Wales. Fortunately for New Zealand that baneful suggestion was not entertained; but Governor Macquarie appointed Justices of the Peace and exercised the functions of Government within the Islands, as did his successor, Sir Thomas Brisbane, down to the time of his proclamation which excluded New Zealand from amongst the dependencies of New South Wales.
