Unsafe ladders being sold on Trade Me have been banned after collapsing under much less than the weight it was claimed they could hold.
Consumer Affairs launched an investigation after a "multipurpose" ladder promising to carry 150kg collapsed seconds after a 90kg man climbed it.
Officials tested similar ladders made of thin aluminium and found all failed loading requirements.
Consumer Affairs Minister Simon Bridges announced a ban yesterday. Fines for anyone who breached it could amount to $60,000 for individuals and $200,000 for companies.
"It is unacceptable that the public should be at significant risk of injury from multipurpose ladders that do not meet Australian and New Zealand safety standards, which is why I have, after consideration, declared an unsafe goods notice," Mr Bridges said.
The ban will be reviewed after 18 months.
