Mercury ore (cinnabar) occurs around Puhipuhi, north of Whangārei, and small amounts were mined intermittently in the first part of the 20th century. In the photograph, a worker is shown filling metal bottles with mercury. Note that he wears no protective clothing. Mercury vapour is now known to be highly toxic.
