A cheeky new tourism campaign promoting Tauranga has reopened regional rivalry by poking fun at Rotorua's rotten-egg smell.
The battle of the Bay of Plenty cities has been triggered by adverts in bar toilets in Auckland and Hamilton.
Slogans include "Smell like Rotorua in here?", above an image of a sandy beach and the Tauranga promotion web address.
Tourism Bay of Plenty boss Tim Burgess said the ads were intended to be "cheeky and irreverent" and play up their toilet-door location. "It's no secret that there's a sulphurous smell in Rotorua and it just seemed to be a nice fit," he said. "It might appear to be a bit on the nose, but at the same time it's paying a compliment when you mention a competitor in an ad."
Destination Rotorua general manager Don Gunn said his rivals from over the Mamaku Ranges were "resorting to toilet humour" but the jibe hadn't put anyone's nose out of joint.
