While this discussion was proceeding in England, Captain Hobson was happily on his way to Sydney, with his instructions rendered still more explicit[46] by further explanation from Lord Normanby, thus eliminating, as far as human forethought could provide, the possibility of misunderstanding as to the extent of his authority, or to the sincerity of the broad humanitarian principles which were to govern his conduct towards the natives.

Reaching Sydney late in December 1839[47] he immediately himself to Sir George Gipps, who entered into the spirit of the enterprise with his characteristic enthusiasm for the service of the Empire. During their official negotiations the final arrangements were completed agreeably to the intentions of the Colonial Secretary. Captain Hobson was placed in the possession of the Proclamation under the Great Seal, by which the Government of New South Wales was extended to any territory which might be acquired as the result of Hobson's mission "in those Islands commonly called New Zealand." Simultaneously he was presented with his own Commission as Lieutenant-Governor of any such territory, and with the proclamations he was to issue in New Zealand, as circumstances rendered necessary or advisable. He was also placed in possession of further instructions from Sir George Gipps, who laid special stress upon the financial relations existing between the two colonies. "My responsibility for the due expenditure of the public money of this colony," he said, "is one of which I cannot divest myself, and where responsibility is there also must be control. The extent to which establishments are to be erected in New Zealand, the salaries to be paid to public officers, and the expenditure of public money on public works, must for the present be fixed by myself on estimates and reports or proposals to be forwarded by you." Close enquiry was also made into the legal question which Captain Hobson had raised with Lord Normanby when seeking fuller information regarding his powers of administration. Hobson desired the power to appoint and suspend Magistrates; to pardon offences and remit sentences, and to exercise original control, which the insular position of New Zealand seemed to demand, but which was seldom conferred upon those holding the subordinate office of Lieutenant-Governor. To this request Lord Normanby had replied that all the powers necessary for the proper conduct of his office would be conferred upon him by acts of the Governor and Legislature of New South Wales. Hobson was unconvinced, but deferentially refrained from pitting his lay opinion against that which he naturally assumed was based upon the wider knowledge possessed by the Department. Sir George Gipps had no such reservations, and at once declared his inability to delegate to another powers which had only been delegated to him.

In communicating his final instructions to the Lieutenant-Governor, Gipps wrote: "With respect to certain powers or prerogations of the Crown, with which Governors of colonies are usually entrusted, it is necessary for me to point out to you that though I am myself authorised by Her Majesty to exercise them in her name, and on her behalf, I have no power to delegate the exercise of them to another. From this, which is an inherent maxim in law, it will, I believe follow:

"(1) That you will not have power to pardon offences, or to remit sentences pronounced on offenders in due course of law, though you may stay the execution of the law.

"(2) That you will not be authorised to suspend officers holding appointments direct from Her Majesty, though you may recommend to me the suspension of them. With respect to persons holding appointments from me you will have the power of suspension, and over such as hold appointments from yourself a power of dismissal unless they may have been previously recommended by you for confirmation in the service, in which case your power will extend only to suspension.

"(3) You will not have power of appointing Magistrates, though of course you will recommend to me such persons as you may think fit to be appointed.

"(4) In the event of the enrolment of a militia, the same will hold good respecting the appointment of officers."

A staff of officials for the due conduct of the civil business of the country was also appointed,[48] even to a small force of policemen, and with an almost prophetic punctiliousness for detail, a Commission was prepared for his successor in the event of Hobson's death, so that there might be no break in the continuity of official control.

With these preliminaries settled, Governor Gipps, on January 14, issued three proclamations: (1) extending the boundaries of New South Wales to New Zealand; (2) proclaiming Captain Hobson Lieutenant-Governor of those Islands, and "calling upon all British subjects to the aiding and assisting of the said William Hobson in the exercise of his said duty"; (3) to put an end to the speculation in New Zealand lands then being openly carried on in Sydney.

The Herald, a frigate of twenty guns, commanded by Captain Nias, lay in Spring Cove, waiting to convey the Queen's representative and his party to New Zealand.[49] At six o'clock on the evening of Saturday the 18th the staff appointed to accompany the Consul joined the vessel, and at a somewhat later hour Captain Hobson himself went on board. Under the influence of a fine N.E. wind, a full moon shining down upon the harbour, the Herald left Port Jackson and headed for the Bay of Islands. Fine weather was experienced in the Tasman Sea and on Sunday the 26th, while a gentle breeze filled the sails and soft zephyrs whispered through the cordage, Captain Nias conducted Divine service on the gun deck, which was attended by the whole ship's company, and "a more beautiful and impressive scene I never witnessed," is the description of the ceremony given by Mr. Felton Mathew, who was coming with Hobson as the Surveyor-General to the new colony. At daylight on the following morning the Three Kings were sighted, and shortly after the mainland came into view. Two days were spent in beating up the coast, and again at daylight on the 29th, the Herald entered the Bay of Islands, drifting with the tide, there being not a breath of wind. All the morning was spent in this tedious process, and it was not till eleven o'clock that the anchor was cast in front of the little town of Kororareka.[50] Across the Bay the Union Jack was flying in front of Mr. Busby's residence, but what most attracted the attention and excited the interest of those on board was the French tricolour floating from a staff upon the hill-side above the township. "What this may indicate," wrote Mr. Mathew in his diary, "we have yet to learn—whether it is merely a French Missionary establishment or whether a French frigate is at anchor in the Bay and has anticipated us, we shall soon discover."
