Before the announcement, 3.4 percent said they weren't investing in MRP, compared with 13.4 percent after the announcement. Some 24.4 percent were considering their options ahead of the Labour-Greens policy release.
Asked whether they would change the amount they would invest, a little more than half (53.9 percent) said they would reduce their intended exposure to MRP, 37.3 percent said they would invest at the same level, and a brave 2.1 percent intended to invest more than before.
"While most seemed likely to proceed, the level of their investment may be reduced as they reacted to the higher perceived risk," said NZSA chairman John Hawkins. "This was not unexpected as capital markets react very negatively to regulatory uncertainty or policy U-turns, even when they may be some distance in the future."
Hawkins said the poll also suggested informed retail investors were broadly satisfied with their access to information and advice about the float, despite criticisms in the media that so many investment advisers are party to the sale that independent financial advice has been hard for retail investors to get.
"The reality was that 62 percent of investors were satisfied in making their own decision," said Hawkins. "Half of those who were seeking tailored advice had been able to obtain it from financial advisers or sharebrokers."
Almost three-quarters of those who answered the survey question thought the 260 page MRP prospectus was well laid-out and informative, which was an endorsement of the new Financial Market Authority rules applying to offer documents, he said.
One-third of those who answered said they thought the document too lengthy and further moves to introduce short form disclosure documents would be welcome.
