"This means tobacco smoke does affect patrons and cafe workers some distance away and smoke drift can also enter your cafe."
She said smokefree dining was common in Australia with some of their smokefree restaurants reporting increased income and patronage.
"It may be some time before New Zealand follows Australia's lead and legislates for smokefree outdoor dining, but why wait?
"Let's go after increased local revenue, look after the health of our staff and diners by protecting them from second-hand smoke and help smokers quit and stay off cigarettes by increasing smokefree environments."
The cafes that took place in the Wairarapa trial were Pukaha Wild Cafe, Iberia, Entice Cafe and Catering, Dish Cafe, Wild Oats, The Village Grinder, 2 Short Whites and Ten O'clock Cookie.
"We are really happy with the results, and super happy that the eight participating cafes are continuing with their smokefree dining choosing to make it a permanent thing," Mrs Tomlinson said.
"All participating cafes enjoyed a very positive response from customers about their smokefree outdoor dining."
She said the PHO had Smokefree signage available free for Wairarapa cafes.
"We don't expect you to police smokers or tell people off, the signage is enough."
