Matai bay had plenty of Ihumaona stings this January.
Found this exceptionally large long finned eel struggling to make its way down stream from lake Wainamu, the stream bed is black sand and seemed to interfere with the eels mucus layer, she was drying up in water far to shallow to swim. After an hour in a large plastic bin with running water she had recovered so I carter her(and several other not so large eels) down to the estuary at Bethells beach where I guessed they were headed and let them decide when they would leave for the pacific islands.
The eel in the photo was 1500mm long and weighed 16kg estimated to be 75 years old but could be around 100.
