The Shareholders Association backs criticism by the Financial Markets Authority that investment documents for recent sharemarket listings have been so long and dense many retail investors may not have read them.
But the association's acting chairman, Grant Diggle, blames the law, not companies issuing the documents.
The FMA yesterday called on issuers of investment statements and prospectuses to "lift their game" after its report on the industry following its guidance note of June last year.
Simone Robbers, head of primary regulatory operations at the FMA, said although there were some positive signs, issuers had some way to go in providing better-quality information to retail investors.
"The disclosure documents for initial public offerings were so long and dense that we doubt many retail investors would have read them," Robbers said. "FMA is concerned that such long documents may in fact have deterred members of the public from investing in the offers."
