Please note:  (updated 29/1/16):   “The test regime for Piha Lagoon is as the same as that for Bethells Lagoon:

  • Carry out routine testing
  • If routine test exceeds the MfE action level (550), erect warning sign without retesting
  • If routine test exceeds the MfE alert level (260), carry out re-tests until either the result triggers the MfE action level for warning sign or becomes clear
  • It routine testing is clear, no sign is erected

The changes in the testing regime/signage criteria are as a temporary means to manage the potential health risks before any decision regarding more permanent health warning. However, the routine tests have all failed so far. The sign appears to be erected permanently. The signs have not been erected at Bethells Lagoon all the time.

So at the moment, no decision has been made to permanently signpost the lagoon, but it is a candidate for this along with the other bottom few sites in the region”

    still inadequate signage about the hazard, why bother doing this ?

  2. The Bounder says:

    So the lag -goon remains unsafe so what shall we do to advise paddlers esp visitors. I know, lets put in signs to show that this area is being monitored and at times may be unsafe, yes lets give visitors the chance to risk their kid’s health by having signs pointing out to sea hidden behind the bank so that the only way to read them is by jumping in the lag goon. Nothing changes….what a waste of time after all we don’t want to scare people or take responsibility.

    Gross! Piha Beach South is marginal and needs retesting sometimes due to the contamination with human faecal matter. Nice swimming spot. NOT!
