Why people convert Auckland to COT time

Scheduling a call from Auckland to COT: a 10:00 AM start in Auckland lands at 4:00 PM in COT the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -18h gap: Auckland and COT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in COT is 3:00 PM in Auckland.
Coordinating a Auckland-based team with COT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM NZDT" is unambiguous; "3 PM" across a -18h gap is not.
With a -18h gap there is no shared 9-to-5 window, so alternate the early start: one week Auckland takes the early slot, the next week COT does.
