New environmental data at Tiwai Pt aluminium smelter shows sea level rise is destroying bores within scores of metres of where 100,000 tonnes of hazardous waste is stored.
Coastal erosion has already shut down one bore used to monitor groundwater for pollution, and threatens to take out a second.
These bores are within five metres of sand dunes, a few metres behind which sits 106,000 tonnes of spent cell liner (SCL) waste - which contains cyanide and fluoride - on a giant concrete pad.
The smelter company has rejected government reports that the sea will rupture its huge landfill with "catastrophic" results within a century, saying its preliminary modelling shows it is safe for 100-200 years.
