"They would say 'that's the wrong outfit or that's too expensive' but they wouldn't say 'why do people need to shop to feel better about themselves?"'
It's the first book to consider the rapid rise of makeover reality television from an audience perspective.
The results came from 110 regular viewers and 20 others who were not fans and were more cynical about consumption, a sentiment more likely to be echoed by New Zealand viewers, Professor Sender said. "I find New Zealand to be a much less consumer-oriented country than the States."
Originally from Britain, Professor Sender lived in the US for 20 years, and relocated to Auckland 12 months ago. "People aren't so ostentatious in general and don't show their money off as much and it's a more casual culture so I would hope that even when people enjoy the shows they are more sceptical about a lot of the content."
In New Zealand, reality makeover shows were more likely to be about houses.
"We're like the Brits, we really care about our homes and the Americans really care about what they look like."
New Zealand also has its own version of Starting Over.
Sian Jaquet, life coach on New Zealand's Starting Over, said she worked on the show because of the integrity behind it.
"It was about working with people who genuinely wanted to make a difference in people's lives."
