SEXY TIME: The Mega Kiwi Sex Survey 2012 has examined sex habits of New Zealanders.

More than 25 per cent of all Kiwis rate themselves as stunners in the sack, though women are more confident in their abilities than men, according to a new survey.

The Mega Kiwi Sex Survey 2012 also shows we're having sex an average of 133 times a year - two to three times a week - and that Tauranga, Gisborne, Palmerston North and Whanganui are the most sexually active areas in the country.

The survey of more than 1500 people showed significant differences in the attitudes of men compared with women.

Of the respondents, only 31 per cent were satisfied with the quality and frequency of the sex they were having while 12 per cent said the quality wasn't what they desired.

Women were more satisfied than men at 34 per cent satisfaction compared with 29, with those who are unsatisfied saying they want more rather than better sex.

Only 3.2 per cent of people are having it more than once a day.

More than 30 per cent of people admitted to thinking about a previous partner during sex and almost a quarter about work.

Others admitted to thinking about food, housework, bills and a celebrity.

When it comes to confidence in the bedroom, women are more pleased with themselves, with 29 per cent rating their sexual expertise as 'excellent' compared to only 25 per cent of men.

Just over half of respondents said they do 'alright' in the bedroom while 21 per cent said they could improve.

People in relationships are more satisfied with their sex lives than married couples and singletons while unemployed respondents were more satisfied than those who were gainfully employed.

One in three people rated the morning as their favourite time to indulge while those in Whangarei apparently prefer lunchtime.

Hastings was the most sexually satisfied region in New Zealand, while Gisborne was the least.

A third of women rate their breasts as their sexiest body parts followed by their eyes, bottoms and legs.

Men are also fond of their eyes (19.5 per cent) followed by their bottoms and smiles then just under 10 per cent rating their genitals.

Women also have sex for the first time a year earlier then men on average, losing their virginity at 16 while they also have more sexual partners, with an average of eight compared with six for men.

"There is argument for some degree of promiscuity in New Zealand sexual attitudes with 1 in 5 respondents to the survey having had 20 or more sexual partners," the survey reads.

More results from the survey are to be released later this year.
