Bid to locate unregistered quarries
Mining safety authorities want public help in locating unregistered quarries after four deaths at sites this year.
At least two of the men killed, died at unregistered work places.
The health and safety council for the mining and quarry sector said it was a bad year for fatalities.
It is aware of about 500 registered quarries.
WorkSafe figures released to RNZ said there could be up to 1200 sites nationwide which could meet the legal definition of a quarry or alluvial mine.
