The new smokefree policy in Hastings and Napier has the backing of the Hawke's Bay Regional Council and Hawke's Bay District Health Board.
The Napier and Hastings councils adopted the policy last year, with the roll-out of signs happening in the first half of this year.
Smokefree is the theme for May for GO Bus advertising. Posters reminding bus users that stops and shelters should be smokefree out to a distance of 10m are also going up.
The policy is non-enforceable and is about encouraging people who wish to smoke to move away from areas the councils have named "fresh air zones", including parks, sports grounds, public entrances to council buildings and footpath eating areas.
Retailers with footpath dining in Napier and Hastings are able to use "fresh air zone" signs and stickers advertising the policy.
