Alcohol companies are reducing their investment in grassroots sport.

A recent Alcohol Healthwatch audit shows only three percent of Auckland rugby union teams have booze branding on uniforms.

Most sponsorships were from local construction, real estate, and sportswear brands.

Executive director Dr Nicki Jackson says concerns the Sale and Supply of Alcohol Amendment Bill will affect grassroots sport, are unwarranted.

Green MP Chlöe Swarbrick's private member's Alcohol harm minimisation bill aims to abolish appeals on local alcohol policies, returning power to communities to decide how many liquor stores can operate in their area.

The second part of the bill will ban alcohol sponsorship of sports and venues and advertising during the broadcasts of live sporting events.

Chlöe Swarbrick joined Heather du Plessis-Allan.
