Does anyone know of a place in Auckland that might have power strips, with North American outlet plugs, but has a NZ plug for the side that goes to the wall. I have lots of electronics that will work on 240v, but they all have North American plugs, and no one sells plug adapters for less than $20 [and they're all so clunky I can't put two next to each other on a power strip].

I have power strips we brought with us from Canada, but they all have breakers on them that pop when you plug them into 240v. So a power strip with North American plugs on both sides would work if it can still handle 240v running through it.
