The Financial Markets Authority has given its tick of approval to the Mighty River share offer document, meaning next week's offer is set to proceed as planned.
In an announcement today, the FMA said it had completed its review of the document and was satisfied it contained the information potential investors needed to make an informed decision.
The offer document was registered last Friday, giving the FMA five working days to review it before the allocation of shares begins.
"The offer document is a significant source of information for anyone thinking of investing in a financial product, and while it's not FMA's role to endorse any offer, we are keen to work with issuers where we can," said Sean Hughes, head of the FMA.
Hughes said the FMA had engaged with Mighty River Power and the Crown well before the offer document was registered because of "the complex and significant nature of the listing".
