NEW ZEALAND The Midlothian, Morison, from Sydney, New South Wales, has arrived off Falmouth, and landed a mail. The following interesting intelligence from New Zealand was received by this conveyance : "On April 2, in lat. 35 43 S., long. 177 56 E., spoke the Mary, of New Bedford (whaler), which reported having seen, three days previously, her Majesty's ship North Star working into the Bay of Islands; also reports that the natives there and the crew of her Majesty's ship Hazard, and the British troops, had an encounter; that the flag staff had been pulled down, and the town of Kororarika burnt; about 100 of the natives had been killed and wounded, and about 18 or 20 of the English; the commander of the Hazard badly wounded. The British residents had all left for Auckland. Quietness had been restored." As the Midlothian merely communicated by a pilot boat, further particulars, in addition to the captain's own report, cannot be obtained. The Midlothian also spoke, on April 6, in lat. 36 5 S., long. 178 56 W., the man of war St Louis, standing N.E.
