Hi Marcus,
Good to here things are happening.

I just typed up a bundle of info for you, saved it to draft while I looked something up, came back to it and it had disappeared into cyber space.
Here we go again.
From memory we also looked at the online form then ended up phoning them, to get a quote for the doors including shipping to NZ.
At first they said we wouldn't want them as the shipping to NZ would be too expensive, but when they realised that on this side of the world we know about shipping costs, they got things under way. We did our payment by credit card, sending them the details in several parts by separate emails. The doors appear to be made by Hehr, but I have not found them on their web site, I assume they are specialist supply only.
There are other manufacturers/suppliers of similar doors over there,

Have a look at this link, it is full of the usual advertising

Frank.

It worked this time.
