Easysteel says that for more than 90 years, it has been supplying the New Zealand
market.
The spokeswoman said Easysteel was not the only purchaser of RHS from Steelforce but that a number of other businesses here purchased the materials.
"With all the attention on steel, Easysteel has been very careful to look at the standards and check certification," she said, referring to the commission's earlier steel investigations.
On December 5, the commission said it had completed its seismic steel mesh investigations into five of the companies.
"Three companies, which cannot be named at this time, have been advised that the commission intends to issue criminal proceedings under the Fair Trading Act. Two other companies have been issued with lower-level investigation outcomes. Fletcher Steel Limited has been issued with a warning and United Steel Limited has been issued with compliance advice. Investigations are continuing into several other companies.
"The commission began investigating seismic steel mesh in August 2015 after a complaint was laid that some steel mesh products did not comply with the Australia/New Zealand standard," the commission said last year.
Fletcher was warned for engaging in conduct that was likely to breach the Fair Trading Act on 19 specific batches of 500E product. The commission was concerned these batches did not comply with the standard because Fletchers' re-testing was not conducted in line with the strict requirements and its quality data recorded some values that were lower than required by the standard.
But the commission was satisfied that the mesh had the strength and ductility required by the standard, so was comfortable with just issuing a warning letter.
