Wikipedia says:
Chinatowns existed on Greys Avenue in Auckland and Haining Street in Wellington up until the 1970s, and there is a growing community in both Christchurch and Dunedin.
Does it mean that nowadays there are no Chinatowns in Auckland and Wellington? The information about Christchurch and Dunedin is vague too. I can't see any places marked as "Chinatown" in NZ on Google Maps.
