I know of a couple :-
Balmain Park Toilets, Oxford Terrace, Devonport
Hauraki Corner Toilets, Jutland Road, Takapuna
Peaches and Cream, Barrys Point Road, Takapuna
K'Rd Video, Karangahape Road, Auckland Central
Yes Peaches & Cream in Manukau have a theatre and private booths with glory holes. We haven't used them yet but my partner and I are keen to have a guy watch us through the glory hole. We might be there this weekend.
