Lake Pupuke is a heart-shaped freshwater
lake occupying a volcanic crater (or
maar) between the suburbs of
Takapuna and
Milford on the
North Shore of
Auckland,
New Zealand. The heart shape is a result of its formation by the linking of two circular craters - a larger one forming most of the lake and a smaller one forming the arm in the northeast. Separated from the sea by less than 200 m at one point, it has a circumference of about 4.5 km and reaches 57 m in depth. It is popular for recreational activities and the lakefront property around it.
