Waitemata DHB has gone from second-worst to the best DHB in the country, when it comes to helping smokers quit.

The latest data for April to June shows the DHB increased its quitting rates by 43 percent, compared to previous quarter.

Chief executive Dale Bramley says the result is a testament to the work of PHOs across western and northern Auckland.

He says 97 percent of smokers in the area are being encouraged to stop smoking during doctors visits.

They're also getting reminders via phone and text.
