More than 2300 Kiwis have signed up online for this year's Dry July.
They will take a month off drinking alcohol, which helps promote responsible drinking, and the social fundraising initiative will raise funds for New Zealanders living with cancer.
So far this year's campaign has raised $95,130.
According to the Tomorrow Project, an organisation charged with changing Kiwi attitudes to drinking, Dry July makes people stop and think about how they drink alcohol.
"Taking a month off drinking - or even thinking about doing that - could encourage us to think about why and how we drink which will likely make for more responsible drinkers long-term," says Matt Claridge, executive director of the Tomorrow Project, .
The best way to learn more about your own drinking is to find out what a standard drink is, or whether your drinking is 'normal', organisers say.
