The only one that I would even consider is the zeus out of those three, but to be honest they are all heavy and over priced-- brands like TNF, Marmot and MH tend to be expensive for what they are selling.

Personally, if I was going to drop $300USD on a down jacket than I would go with top quality: Nunatak or Feathered Friends.

For half the price-- look at Montbell-- not sure if they would ship to NZ, but you can score some of their down jackets for around $100USD excluding shipping from the gear swap forums and e-OMC currently has the UL Down Inner listed for $125USD excluding shipping. This is the jacket that I use in three-season colorado and combined with lightweight baselayer I am comfortable to around 32F.
