The mercantile pound (1304) of 6750 troy grains, or 9600 tower grains, derives from this pound, as 25 shilling-weights or 15 tower ounces, for general commercial use. Multiple pounds based on the same ounce were quite common.
While the far north has subtropical weather during summer, and inland alpine areas of the South Island can be as cold as -10Â°C (14Â°F) in winter, most of the country lies close to the coast, which means mild temperatures. The average New Zealand temperature decreases as you travel south.
March can be some of our best weather. New Zealand's weather can be extreme and the further south you go generally the weather will be cooler, expecially at night. So be prepared to have a fleece, jacket, long pants, shorts and t shirts. Northern NZ's weather is more moderate. As a rule South Island is hot/cool but dry. North Island warm/humid and wet.
