ORDER IN COUNCIL.

At the Government Buildings, at Wellington, this eleventh day of December, 1911.

Present:

THE RIGHT HONOURABLE SIR J. G. WARD, BART.,
PRESIDING IN COUNCIL.

WHEREAS, there being no Harbour Board empowered to grant the license hereinafter mentioned under the Harbours Act, 1908 (hereinafter called “the said Act”), William Douglas Meiklejohn, of Devonport, Auckland (hereinafter called “the licensee”), has applied to the Governor in Council for a license under the said Act to occupy a part of the foreshore of Rangitoto Island, Auckland, in order to erect and maintain a wharf thereon; and, in accordance with the one-hundred-and-fiftieth section of the said Act, has deposited a plan in the office of the Marine Department, at Wellington, marked M.D. 3760, showing the area of foreshore intended to be occupied, and the manner in which it is proposed to erect the wharf: And whereas it has been made to appear to the Governor in Council that the proposed work will not be or tend to the injury of navigation, and the said plan has, prior to the making of this Order in Council, been approved by the Governor in Council: And whereas it is expedient that a license should be granted and issued to the licensee under the said Act, for the purpose aforesaid, on the terms and conditions hereinafter expressed:

Now, therefore, His Excellency the Governor of the Dominion of New Zealand, in pursuance and exercise of the power and authority conferred upon him by the said Act, and of all other powers and authorities enabling him in that behalf, and acting by and with the advice and consent of the Executive Council of the said Dominion, doth hereby approve of the object for which the said license is required by the licensee as aforesaid; and, in further pursuance and exercise of the said power and authority, and with the like advice and consent as aforesaid, doth hereby license and permit the licensee to use and occupy that part of the foreshore on which the wharf is to be erected, as shown on the plan so deposited as aforesaid, for the purpose of erecting and maintaining the said wharf thereon, such license to be held and enjoyed by the licensee upon and subject to the terms and conditions set forth in the Schedule hereto.

SCHEDULE.

1. In these conditions the term “Minister” means the Minister of Marine as defined by the Shipping and Seamen Act, 1908, and includes any officer, person, or authority acting by or under the authority of such Minister.

2. The concessions and privileges conferred by this Order in Council shall extend and apply only to the part of the
