Lake Pupuke is a freshwater lake occupying a volcanic crater between the suburbs of Takapuna and Milford on the North Shore of Auckland, New Zealand. Located less than 500 m distance from the sea at one point, it has a circumference of around 6km and reaches about 60m in depth. It is popular with picnickers, paddlers, rowers, yachtsman, divers and wildfowl and there is a café adjacent to the old pumphouse. The increasing popularity has led to recent concern over water quality.

Other similar craters in the Auckland Volcanic Field were either buried by later eruptions, or breached by erosion as rainwater collected and overflowed the edge of the crater. Lake Pupuke remains a lake because water can escape through cracks in lava flows reaching under the crater wall, creating a series of freshwater springs along the beaches between Takapuna and Milford

  • More like 250 metres from crater to sea. The crater has no cone because it was formed by the sea originally entering the crater - the violent interaction typically prevents a cone forming in such cases. Auckland had about 50 significant volcanic cones. Recent discoveries suggests about another 50 very small cones not large enough to be seen at a distance.
  • I like volcanoes GET A PERM!!!!!!!!!!!!!!!!!!!!!!!
