FYI updated Amex offer - $800 bonus APD on payment of $395 fee and fairly small min spend, still get the complimentary return flight. So perhaps circa net $600 NZD on offer for all - pretty good deal!

PS - I've no involvement with amex other than as a customer but I've found them good to deal with and thought you all might be interested
