NZS 3604, first published back in 1978 and revised in 1981, 1984, and 1990, is being revised again. As always, the revision is controversial because it affects many interested parties with sometimes conflicting interests. The revised draft for comment was prepared under contract to Standards New Zealand by Mr Ernest Lapish of CLC Consulting Group, Pakuranga, Auckland. Ernie also produced the draft for the very first NZS 3604 so has a vast amount of experience in both writing and using codes.
