I emailed David earlier in the year and he said "we may sell to NZ soon". I'll email again once the F16V4 is available but I guess if more kiwis are interested he will enable it. Otherwise I'll have to use YouShop.
I'm going to order 15m of the ebay hose for my arches this year, seems like there isn't a good option locally. I can make it a bigger order if any other kiwis want some. @Mark_M Is there any reason other than cost why you were avoiding buying off ebay? They seems to ship to NZ
