I think this is what you want:
4.9.8 The phraseology “NO APPROACH SPEED REQUIREMENT” will be used
by a radar controller to cancel the requirement for maximum 250kt IAS
below 10,000ft within 30NM of Auckland, Wellington, or Christchurch
International airports, and also any initial approach speed requirements
published on STAR charts. Any speed requirement on final still applies.
4.9.11 Unless otherwise specified, a clearance for a visual approach
terminates any ATC speed requirement in place including published
requirements being complied with or yet to be acted upon.
