Water in New Zealand

Water is relatively abundant in New Zealand due to the temperate climate and maritime weather patterns.

In recent years, water pollution and draw-down of aquifers have become important environmental issues in New Zealand.

In New Zealand, there are more than 425,000 km (264,000 mi) of rivers and streams and about 4,000 lakes and over 200 underground aquifers.

[1] The reliable supply of good water is an important economic advantage for New Zealand, but its quality and availability is declining.

[2] There are 3,820 lakes in New Zealand with a surface area larger than 1 hectare (2.5 acres),[3] and are of varying types and origins.

Hydroelectric reservoirs are common in South Canterbury, Central Otago and along the Waikato River.
