Janet, do not be afraid to go the New Zealand in midsummer. We, too, were
both teachers and went to Australia twice in July and New Zealand once
in July. Marvelous!! The weather was perfect (much better than being in
hot, humid summer in Baltimore), with really pleasant temperatures (one
member of our party wore shorts the whole time--we did not, but needed
nothing more than a sweater and weatherproof jacket). Plus it was sunny,
blue sky most of the time in both places (maybe we were just lucky?).
But I know if I were to go again, I wouldn't hesitate to go on midsummer.
Plus we were able to do all we wanted to do without long waits. Cheers,
