HN, or holder number
A holder number (HN) is a unique identifying number assigned to investors who buy shares on the NZX through an investing platform rather than a broker. It specifically identifies each shareholder as the owner of a particular portfolio of securities or shares. Companies listing on the NZX may choose to issue shares through ComputerShare or Link Market Services, so an investor’s HN is specific to one of these registries. Shareholders with investments across both registries - as with a CSN - may have more than one HN. An HN and a CSN have similar purposes but are not quite the same. Both are unique identifiers used by the NZX. The HN specifically identifies a shareholder as the owner of a portfolio of securities, while the CSN is common to the NZX, and distinguishes one investor’s holdings from another’s.
