NZ Building Act to battle Legionella

Following the recent outbreak of legionellosis in Christchurch, New Zealand, the Department of Building and Housing has reminded building owners and managers of their health and safety responsibilities under the Building Act. Published in the New Zealand Building Code Handbook as amended in April 2004, the model compliance schedule requires monthly testing for the presence of total bacteria and Legionella bacteria. Test results for Legionella greater than or equal to 1000 cfu/ml (colony forming unit/million) should be notified to the District Health Board within 48 hours. Failure to comply with a compliance schedule may invoke fines of up to NZD 200 000.
