Australian company hits back over safety of aluminium panels

An Australian company is hitting back over the major safety questions raised in New Zealand about aluminium panels used to clad the outside of high-rises. Certmark of Queensland says it's proved its certificates are good enough, and a top fire engineer should not have faulted them. In a report leaked to RNZ News, engineer Tony Enright called for all Certmark's certificates covering aluminium composite panels to be suspended. Phil Pennington reports.
