A wide-ranging investigation has been launched into online traders after an Auckland man received serious injuries when a ladder he bought off Trade Me collapsed "like plasticine" within seconds.
The Ministry of Consumer Affairs said the 4.7 metre multipurpose aluminium ladder was branded safe for workloads of up to 150 kilograms.
Its buyer was seriously injured when it collapsed just seconds after he climbed it for the first time.
Ministry of Consumer Affairs Principal Advisor Martin Rushton said tests showed the aluminium on the unbranded ladder was only 1.2 millimetres thick.
"The seller could not provide a valid test certificate to show it had passed safety testing.
