I went to get some paint made up and had a sample of the colour I wanted. The man was very rude, acting as if he was annoyed at me because I asked for the cheapest way of doing so (it was just to fill in some spots on wall). Apart from that, I've always had good service and the staff willing to help. It is great that there is a cafe adjoined too, so you can get a coffee and something to eat before/after.
Service with a smile - staff always available to help with any enquiry; if they do not know they will find the information 'on the spot'. Good selection of products usually cheaper than most other stores with same product. I personally highly recommend Timaru Mitre 10 Mega
