I thought I'd make a posting here so that we few Kiwis can exchange shopping hints.
I have just bought a 700 ml microwavable thermal lunch container from Kathmandu. It was 30% off, down to $12.50. Here it is with its lid off and sitting beside it.
The 700 ml refers to the volume without the divided insert, I calculate that each side of that holds about 300ml. I think it'd be good for making yoghurt too; hopefully I can find a suitable non-divided insert.
I also found, in Spotlight, wide fluoro elastic in orange, green, and pink. Would be fine for making bento belts if you want fluoro ones!
The only other places I know where you can get bento supplies are the Japanese shops near the Council Chambers in Queen St in Auckland.
