Converting Hawaii Standard Time to New Zealand Standard Time
Hawaii Standard Time (HST) and New Zealand Standard Time (NZST) are separated by a 22 hours time difference. NZST is 22 hours ahead of HST. HST is UTC-10, used in United States, while NZST is UTC+12, used in New Zealand.
When converting from HST to NZST, the key reference points to remember are: 9:00 AM HST equals 7:00 AM NZST, 12:00 PM noon HST equals 10:00 AM NZST, and 5:00 PM HST equals 3:00 PM NZST. The conversion table above shows every hour of the day mapped between these two time zones.
Scheduling Across HST and NZST
For professionals scheduling meetings between HST and NZST, finding overlapping business hours is essential. Standard business hours are typically 9:00 AM to 5:00 PM in each time zone. Given the 22 hours difference, the window of overlap may be limited, making early morning or late evening calls necessary for one party. Use the highlighted working hours in the conversion table above to quickly identify suitable meeting times.
Daylight Saving Time Considerations
HST does not observe Daylight Saving Time, maintaining UTC-10 year-round. NZST observes DST, switching to NZDT (UTC+13). During DST transitions, the time difference between these zones may temporarily change by 1 hour. Always verify the current offset during spring and fall transition periods.
