THE COLONY OF NEW ZEALAND. Some important official documents have been published, from which it appears that the Government, in pursuance of the act passed last session, have granted a new charter for the regulation of New Zealand. The charter repeals that of 1840, and creates powers, municipal, legislative, and administrative, for New Zealand. The instructions under the Royal signet and sign manual exhibit the constitution of the colony, "in all the detail in which it has been possible to prepare it in this country." One commission appoints Captain Grey Governor-in-Chief of New Zealand, and Governor of each of the two provinces into which the islands are; pro tempore, to be divided. The other appoints Mr. Eyre Lieutenant-Governor of these provinces. As its second estate, each province is to have a Legislative Council, and the Legislative Council will be nominated by the Crown. As its third estate, each province is to have a House of Representatives. This is to form the popular element of the constitution, and to embody the doctrine of self-government. In the choice of representatives, the principle applied is that of double election. A common council is to elect the representative; the borough is to elect the common council. The formation of boroughs involves a survey of the colony, a registration of its lands, and a division of the whole country into muncipal districts. A Governor-in-Chief, a Legislative Council of the General Assembly, and a House of Representatives for the General Assembly, will be paramount to the provincial legislations (or assemblies) in the way that an American Congress is paramount to tile legislations of the states. Letters from Wellington of July 25, announce the capture of the native chief Rauparaha, by Captain Stanley. Captain Stanley timed his visit to Rauparaha's pah so well, that he took Rauparaha, Charley, and three others before they had time to strike a blow ; he also seized some 37 stand of arms and 6 or 7 kegs of powder. Rauparaha's men all decamped, and are supposed to have gone to Rangihaietta, in number about 35. Rauparaha himself, and Charley, and the three others are all safe on board the "Driver", in irons. This is the most decisive step Governor Grey has yet taken. Rauparaha and Charley were both at the massacre of Captain Arthur Wakefield, at Wairoa; and the settlers are in perfect ecstacy at this bold policy of the Governor.
