I used to go to those drop- in places in Dunedin all the time we lived there (HQ had several places in town) and apart from one occasion I was usually quite happy with the cut- and they cut the hair "dry", so no washing beforehand (which I do every morning anyway), just spraying it wet. That cost $20 in the beginning, going up to $23 in the end, I think.
In Blenheim I go to a hairdresser which was recommended by a freind and I pay $38 for washing, cutting and blow- drying.
But that's Blenheim, I suppose
..., not Auckland
