mass deaths of NZ Smelt at the estuary of the Otaki River
The Cawthron Institute has confirmed there is there is no sign of harmful algal blooms in the water samples. The
evidence gathered suggests natural death from a mass shoal stranding in the estuary. No sources of contamination or
pollution have been established and Regional Public Health has confirmed they are comfortable with us lifting the
previous recommendation in relation to not fishing, gathering or playing in the estuary - they have had no related
reports to them of sickness/illness. So people may resume normal activities in the estuary.
