Problems caused by immigrant German and common wasps in New Zealand, and attempts at biological control
Barry J Donovan
New Zealand consists of two main islands orientated in a north-south line and numerous smaller islands which lie in the south-west Pacific about 2000 km from the south-eastern coast of Australia. The main islands lie between 34°S and 47° S, and 166°E and 179°E. On the globe of the world, New Zealand is about opposite Portugal and Spain. The first people to settle in New Zealand, who arrived from Pacific islands to the north about 1000 years ago, found a country of temperate climate with more or less even rainfall throughout the year. Extensive forests covered most of the North Island, while about a quarter of the South Island was forested. The remainder was extensive grasslands or high mountain snowfields.
