SPH (Substantial Product Holder) notices are designed to inform market participants about people or organisations that have large shareholdings in listed issuers.
They are provided to promote an informed market and deter insider conduct, market manipulation and secret dealings in potential takeover bids. NZX guidelines state this is “to ensure participants in financial product markets can access information about the identity and trading activities of anyone who is entitled to control or influence the exercise of significant voting rights in a listed company”.
“Timely, accurate disclosure is important to promote these purposes.”
An NZX spokesperson declined to comment further, referring the Herald’s questions to the Financial Markets Authority.
An FMA spokesman said it did not generally comment on individual entities or whether it was investigating an entity.
“However, it is important that market announcements are accurate and any errors are remediated quickly. The FMA will be following up with BlackRock to understand what happened and any lessons that can be learned from today’s incident.”
