One observation about this 22-year-old quote:  New Zealand (then and
now) observed summer time for roughly half of the year, so "which is
12 hours ahead of GMT" was only correct for the southern hemisphere
winter; in the summer New Zealand was 13 hours ahead.

If the observation of a 6 hour difference between McMurdo and Vostok
was in the southern hemisphere summer while New Zealand was on
summer time, that observation could be consistent with Vostok
observing UTC+7 at the time.
