I have gotten bug bites in late May/early June. One time it was probably from being on the balcony at AKL in the evening, got a few on my feet/ankles, and they were pretty bad. Ended up having to go to first aid for some cream the next day. I don't usually use bug spray, but now I plan to bring it if I'm going to be at AKL or by water in the evenings.
I wouldn't say it's bad, and most of the time I don't get bitten.
