Those are correct.  I just looked up New Zealand on
<http://www.worldtimezone.net/wtz020.php>
for example, and it shows NZST as "GMT+12", plus one more for Daylight Saving
Time.

Likewise,
<http://en.wikipedia.org/wiki/Wellington>
lists Wellington's time zone as
> Time zone      NZST (UTC+12)
> - Summer (DST) NZDT (UTC+13)
