Bedpost quickly found in their catalogue a duvet inner the exact measurements I wanted(Californian King 110cm x 280) after I had spent about 20 minutes at Harvey Norman with them fluffing around and saying those are not the correct measurements for a Cali King and I would likely not get one in NZ. In fact, I have found that it varies in some countries. No drama with Bedpost, they phoned me after just 2 days saying it had arrived.
