The number of people buying lotto tickets was not so much of a concern, rather how many people were buying tickets who could not afford it.
"The problem with lotteries comes when people are in dire financial trouble and see this as a way out, or when people are chasing their losses in other forms of gambling.''
In the past few years the number of people buying lottery tickets had gone up in general, while pokies had been trending down, he said.
"The bulk of that is about big jackpots; big jackpots drive spending. When the jackpot gets beyond the certain point, which in our analysis is about $15 million, then spending goes up dramatically.
"We've certainly seen over the last couple of years, many many more of those big jackpots than statistical lotteries say there should be.''
The Roy Morgan Research also found 29 per cent of women and 20 per cent of men purchased a scratch ticket in an average three month period in the 12 months to January 2012.
The next most popular gambling activity was pokie machine gambling, with 10 per cent of both men and women chancing their arm.
Men are more than twice as likely as women to use a TAB and the internet to place a bet.
Mr Ramsey was not at all surprised by the research and said it was in line with what was happening in society.
"Gambling has become a really normalised part of New Zealand culture and I think if I do have a concern about lotteries, it's about the way that the massive amounts of money that lotteries spend on advertising ... actually promotes all forms of gambling.
