We have are a plumbing drainlaying and gas fitting from Auckland but have a van set up in Christchurch for some of our contracts. We will happily send a qualified plumber / gas fitter to help with anything. Not sure of the road access for the van to get to the affected areas but we are happy to help where we can. Planning on heading down Boxing Day. Contact us on 0800 968 775 or email Amanda accounts@plumbuilt.co.nz
