"People tend to do the same thing over and over again expecting to get a different result, but it doesn't work that way in real life."
A slightly higher number of men (22.6 per cent) managed to keep the resolutions they made for 2011, compared with 20.5 per cent women.
Ms Kirton said she used to make New Year resolutions before she became a life coach, but now believes in "more strategic life plans".
"I have made concrete plans about things like where I want to be with my work career and my family life in the new year, but I wouldn't call them New Year resolutions as such," she said.
"If a person doesn't have some steps in place on how they are going to achieve their resolutions, then the resolution is just a thought that wouldn't transpire into anything."
Women formed the majority of those wishing to lose weight (29.2 per cent) and eat less (18.1 per cent), compared with men who made up only 20.9 per cent and 10.7 per cent.
However, the top wish for the New Zealand man was to spend less (27.5 per cent) - something that 15 per cent of women had as their resolution.
Ms Kirton, who runs Life Abilities, said the findings were "not at all surprising".
"For women, the weight issue is always the top, but I would think that for men, it's either less spending or to curb their wives' spending on their card.'
She said, however, that people would likely look at relationships and career as more serious life goals.
The poll was taken between December 9 and 16, with a sample size of 500 respondents.
