I recently moved to Zurich and used 'The Moving Company' who I would be happy to recommend. I was in the fortunate position of having work pick up the bill but the quote from Crown was significantly higher than any others I got so it would probably pay to shop around - $6k strikes me as top dollar.

Most NZ agents have tie-up's with agents overseas (Harsch handled the CH end of things with my stuff) and so there is no need to rely on the multi-national approach of Crown.

You will also find that shipping gets relatively cheaper as the volume increases as there are a large amount of fixed costs (organising shipping, customs clearance, general admin etc) that do not really increase with the volume and so I would get quotes for a couple of different volumes and then judge whether it is worth bringing more.

Good luck with the move - you might want to go travelling en-route as your stuff will take 8-9 weeks to arrive !!!!
