I think she should be allowed to go over as long as she takes out private medical insurance. If she really wants to lose the weight she will - i would suggest working in a rural community in Africa for a month and it would drop off. NZ gov's perogative I guess.

Obesity is a such an issue now. If government gets tough it is showing a lack of compassion and discrimination. if nothing is done then the government if failing to tackle the issue.
I can't see how a government can win.

my friend is tiny - petite... and she feels discriminated against because she has to pay for excess baggage when she weighs half the amount of many passengers.
So she advocates that people's allowence on planes should include their body weight!
