Hamurana is a settlement and area of natural springs on the northern side of Lake Rotorua, in Rotorua Lakes within the Bay of Plenty Region of New Zealand's North Island.

[4] The main spring is 920 feet (280 m) above sea level and is approximately 15 metres (50 ft) deep.

It produces an estimated 4 million litres of crystal clear water per hour at a fairly constant temperature of 10 degrees Celsius.

The spring water travels down from the Mamaku Plateau through underground aquifers, taking 70 years to get here.

[5] In summer the stream is home to rainbow trout who prefer the cooler temperature of the spring water.
