Three families were grieving last night after a horror day on the water brought three separate drownings.
A male swimmer in his 50s died after suffering a heart attack while competing in the 2.5km Taupo Epic open water swim yesterday.
Organisers said the swimmer got into difficulty and attempts to resuscitate him by the water safety team and St John paramedics were unsuccessful.
In Tauranga, a fishing trip turned to tragedy yesterday after a 51-year-old Aucklander drowned while setting flounder nets in an estuary.
The man and a 49-year-old friend from Tauranga had been wading in thigh-deep water, setting out flounder nets near Tye Park, Welcome Bay, about 1.30pm.
