No swearing, turning up late, unreasonable demands, fits of tears, handbag-throwing or assistant-thumping for her.
But, according to one talking head who was stopped in a shopping mall, she was supposed to be not just a fashion model but a role model.
Really? Which models would you want your children to grow up to be like? I can't think of one from the roster of self-absorbed, superficial, dim and vain individuals in the profession who I would look to for advice on anything except how to be a giant pain in the butt. So Rosanagh can stop worrying about setting an example. No one else in her line does.
Her biggest mistake was to express her regret for what had happened. She missed a chance to exploit a publicity opportunity that money couldn't buy and brand herself as a bad girl.
The Top Model producers were not so naive. They knew a potential ratings booster when they saw one.
No wonder a show functionary, apparently protecting her from the media, explained to a news crew that "we're covering it Friday night in our show - so we don't want you to bust us".
On a day when one or two other things happened here and around the world, this story led the 6pm news on TV3 - the network that screens New Zealand's Next Top Model.
How lucky Rosanagh's shame came to light three days after reports of poor ratings for the show and three days before the final was to air.
DEADLY NZ APPLES
South Australia is looking at setting up quarantine areas and road blocks to protect itself from marauding hordes of deadly New Zealand apples.
The moves were proposed after a shipment of New Zealand fruit was found to contain "leaf matter" - presumably a leaf - and an apple leaf-curling midge. The items were picked up in screening on this side of the Tasman. The apples had not even left the country.
As part of the agreement to allow New Zealand apples into Australia, a rigorous screening process was established to allay fears about biological hazards entering that country with the fruit.
Within two weeks of the market being opened that expensive and thorough system found two items and stopped apples being sent to Australia.
In other words, it did what it was supposed to do and protected the delicate Australian apples from the burly New Zealand greeblies.
But instead of defending local growers and calling the Australian reaction the transparent piece of politics it is, our Agriculture Minister, David Carter, let loose a string of absurdities. New Zealand growers have not, as he says, had 90 years to prepare themselves to export to Australia. For most of that time the issue was dead in the water. They've got themselves a system that worked in good time. He was also "disappointed the industry wasn't up to scratch". Well, I hope the industry feels just stink about that.
New Zealand growers should be commended for doing a great job in the face of Australian resistance. And Carter needs to show some Rugby World Cup spirit and stand up for the people he is supposed to represent.
LUCKY DIP FOR NUMBER THREE
Hilary Calvert, whose shift of allegiance from Rodney Hide to Don Brash in April secured Brash the leadership of Act, cannot be surprised that her new boss dropped her from the party's recently announced candidates list. It would have been obvious even to Brash that she can't be trusted to support a leader.
That list, by the way, must be the first in the history of MMP to be issued with a lucky dip "your name could be here" blank space at the No3 position.
