gmball: I'd recommend looking at the Kiwibank Airpoints Platinum Mastercard. Accepted in more places than Amex, annual card fee is $150 vs $395, same earning rate of 1 airpoints dollar per $75 spent, 1 status point per $200 spent.

Plus added benefits such as 1 Air NZ Koru lounge pass per $20K spent and discounted Koru club membership.

And supports a NZ business rather than a overseas conglomerate :-) 

Wow. $20,000 for one lounge visit?! I'd expect naked girls delivering very personal services for THAT much money per visit!! ;-)

Spend 20K on your card over the course of a year and you receive a free lounge pass. For those of us who use our credit cards for business purposes, its normally several lounge passes per month which certainly makes it worthwhile. Not to mention several hundred airpoints dollars each month also :-)
