This can get very messy. If you earn elite status (which you probably will with a few NZ flights in the mix), how will they account for the bonus points you earn, especially if you have some personal travel in the mix? Does their policy also apply to credit card charges you make and get reimbursed for if you use an airline affinity card? Or airline points you might earn staying in a hotel? Where does it end? I agree with the above posters about using this as a negotiating tool when you set your fees so you can retain control over your points.
