Does the gap change during the year?

Yes, because of daylight saving. Until 4 Apr 2027: IRST is 9 h 30 min behind NZST. From 4 Apr 2027 to 26 Sep 2027: IRST is 8 h 30 min behind NZST. From 26 Sep 2027 to 2 Apr 2028: IRST is 9 h 30 min behind NZST.

NZST next changes its clocks on 4 Apr 2027 (back 1 h, to UTC+12), then on 26 Sep 2027 (forward 1 h, to UTC+13). IRST does not change its clocks.
