I shopped at Photo Warrhouse on Great North Road recently. The staff were friendly and helpful, the person I was dealing with spent a fair bit of time helping me pick out a new camera bag. They had a table set out so I could put all my gear in it to see if it what I needed. Quite useful!
I spent nearly two hours at Auckland Camera farting around with bodies, lenses and grilling various sales staff when deciding between the Fuji X-T1 and Olympus OM-D1 recently. The staff were friendly, helpful, tolerant and reasonably knowledgeable.
Happy enough to visit them again next time I need to test something.
