What is KST in NZST?

New Zealand Time is 4 hours ahead

Korea Standard Time is on UTC+9:00 and New Zealand Time is on UTC+13:00 right now. New Zealand Time is on daylight saving, so its clocks read NZDT. The gap changes during the year — see below.

When the difference changes

Korea Standard Time and New Zealand Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

Now – April 3, 2027New Zealand Time is 4 hours ahead
April 3, 2027 – September 25, 2027New Zealand Time is 3 hours ahead
September 25, 2027 – onwardsNew Zealand Time is 4 hours ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

Korea Standard Time

No clock changes

Korea Standard Time stays on KST all year, so its offset from UTC never moves.

New Zealand Time

Sunday, April 4, 2027

Clocks go back one hour — 3:00 am becomes 2:00 am local time, and the zone is on NZST after that.

Scheduling between the two
