Steel & Tube Holdings has pleaded guilty to 24 charges of making false and misleading representations about its steel mesh products and will be sentenced in March.
The NZX-listed steel products maker faced 29 charges of breaching the Fair Trading Act in a prosecution brought this year by the Commerce Commission.
That followed a complaint laid in 2015 about mesh used in housing and driveway construction not meeting required standards.
A spokeswoman for the regulator confirmed the guilty plea in an emailed statement.
Steel & Tube entered the plea on August 15 in the Auckland District Court, three days before the company reported a 22 per cent drop in annual profit, which acknowledged the prosecution and included costs, penalties and fines that could be imposed within its $4.8 million of provisioning.
