Tunnelling under Waitematā Harbour in Auckland may release cancer-causing erionite

    Robert Storman

    I wonder if there are similar cases in other parts of the world? Tunnel workers will probably be the first ones facing the risk.

    Researchers in New Zealand warn of erionite, a cancer-causing mineral "worse than asbestos", being released from rocks during tunnelling works.

    Auckland Mayor has recently announced plans for a tunnel crossing under the Auckland Harbour (Waitematā Harbour). The construction is to start only at the end of the decade. Auckland University researchers think the risk is not ignorable.

    Erionite is said to kill by causing mesothelioma, just like asbestos.
