Why people convert Istanbul to Auckland time

Scheduling a call from Istanbul to Auckland: a 10:00 AM start in Istanbul lands at 8:00 PM in Auckland, so you can confirm the slot without doing the arithmetic yourself.
Handling a +10h gap: Istanbul and Auckland 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 Auckland is 7:00 PM in Istanbul.
Coordinating a Istanbul-based team with Auckland 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 TRT" is unambiguous; "3 PM" across a +10h gap is not.
With a +10h gap there is no shared 9-to-5 window, so alternate the early start: one week Istanbul takes the early slot, the next week Auckland does.
Auckland: Clocks fall back on Sat, Apr 3, 2027. Any meeting series spanning that date will shift by an hour in local time.

About TRT (Turkey Time)

Turkey Time (TRT) is fixed at UTC+03:00 all year. Turkey abolished seasonal clock changes in September 2016, moving to a permanent UTC+03:00 so the whole country stays on what was formerly summer time. That leaves Istanbul, which sits close to 29°E, on an offset well ahead of its solar time — sunrise in mid-winter comes after 08:30 local. TRT shares its offset with Moscow Standard Time, Arabia Standard Time and East Africa Time, so Istanbul is level with Moscow and Riyadh all year and one hour ahead of Central European Time during the European winter.

About NZST (New Zealand Standard Time)

New Zealand Standard Time (NZST) is the standard time zone for New Zealand and its dependencies. New Zealand is among the first countries to see a new calendar day. During summer (September to April), clocks advance to New Zealand Daylight Time (NZDT, UTC+13:00).

Best time to call between Istanbul and Auckland

With a +10h offset there is no overlap inside a normal 9 AM – 5 PM day. Auckland opens at 9:00 AM NZDT, which is 7:00 PM in Istanbul, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Istanbul and Auckland have no shared working hours because of the +10h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Istanbul is 10 hours ahead of Auckland (TRT UTC+03:00 → NZDT UTC+13:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
