New Zealand is a country with mild temperatures, moderate rainfall, and abundant sun. The following is a brief sketch of its temperature and rainfall.
Summers are moderate with no station recording more than 77F (25 C) as high temperature. At Bay of Islands it is 77 F (25 C), at Auckland and Rotorua it is 75 F (24 C), at Christchurch and Queenstown it is 72 F (22C) and at Wellington it is 68 F (20 C). The winters are also very mild with high temperature of 60 F (16 C) at Bay of Islands, 59 F (15 C) at Auckland, 55F (13 C) at Wellington, 54 F (12 C) at Rotorua and Christchurch and 50F (10 C) at Queenstown.
The precipitation in New Zealand is moderately heavy and is uniformly distributed throughout the year. The best example example is Christchurch. The highest rainfall is recorded in the month of May which is 2.75 inches (70 mm) while the lowest rain is recorded in the month of September which is 1.69 mm (43 mm). So it is evident that every month at Christchurch gets about 2 inches (50 mm) of rainfall which is more than sufficient to sustain forests since due to low temperatures, evaporation is low. The well distributed rainy accounts for the thick forests which cover most of New Zealand.The interesting thing is that despite a fairly uniform rainfall, most of New Zealand has more than 2500 hours of sunshine annually.
In short, New Zealand has a moderate and suuny climate with no extremes of temperatures and having abundant rainy to sustain plantation.
