Try H.I.S., they are a huge Japanese travel company who have been dealing with Japanese in the UK for about 20 years. They are now breaking into the non-Japanese market here. Very good for VS combinations with other carriers and fares via Asia.
http://www.his-euro.co.uk/english/tarif ... /index.htmThey also have an office just down from Piccadilly Circus so you can actually go in and talk to someone in the flesh! No call centres in far off lands so you can meet your agent. Very Japanese level of service so you should be well looked after.
ETA just had a look and it looks as if they have Aukland flights for £797.
