Ms Douglas recruited a group of 18- to 22-year-olds to take part in focus groups and interviews exploring their use of grooming products and attitudes towards cosmetic consumption. The study indicated young men's awareness of their appearance was increasing and appearance was becoming important at an earlier age.
Dr McNeill said the men were happy to use grooming products, but under rules that fitted their image of masculinity.
"We don't want to give the impression that we have a country of men open to wearing mascara and eyeliner. We do have a country of young men who are open to using grooming products while not wanting to take the manliness out of being a man.
"It was okay to have about five different products in your cosmetic arsenal, but unless you have a skin problem it was not justifiable to have more than that.
"The group talked about general consumption becoming feminised, too," added Dr McNeill. "For example, they said the fashionable clothes in the men's shops are all tight, but if you have a more traditionally masculine body type you may not feel comfortable in those clothes ...
"On the other hand, a few of them talked about the prevalent fashion for facial hair as an attempt to claim back the manly image. One summed up the conflict by saying, 'Men want to be the pretty boy to the ladies, but around other men they want to be the rugged man."'
The study showed the largest influences on whether they bought grooming products were their mothers and to a lesser extent their girlfriends.
"The research revealed really positive things about the New Zealand male," said Dr McNeill. "They have worked out how to balance the notion of being manly with using products that are good from a hygiene or self-care perspective, but that could also be seen as beauty products."
