The proposed new structure of the equity market would see two tiers of issuer on the main board with slightly different requirements for smaller equity issuers, such as using NXT's key operating metrics as a pathway to building a stronger culture of disclosure for earlier stage companies.
The document said its three existing equity boards aren't meeting the needs of smaller companies, and NZX holds the view that different settings can be achieved in a less complicated market structure.
NZX hopes to reduce compliance costs for issuers by making it easier to manage disclosure obligations with greater support, streamlining processes such as capital raisings for issuers which reduces the expense of external advisers including law firms and underwriters.
The other leg to the listing rules rewrite is to enable a broader range of products, with the existing framework hindering the listing of managed funds on the bourse. It's considering creating bespoke rules for managed investment schemes to encourage an area "which is under-developed compared to global peers and presents a strong opportunity for market development."
The company also wants feedback on whether there's demand for listing depository receipts, which are securities typically backed by a foreign-listed company's shares.
"NZX is in the unique position of being the first market in the world to open for trading each day," the paper said. "This provides an opportunity for trading in depository receipts of overseas listed securities prior to other markets opening, and has the potential to provide more investment opportunities to New Zealand investors."
The company's shares dropped 1.7 per cent to $1.17, and have gained 13 per cent this year.
