Texsys said that more than 200 invites have been posted in temporary toilets in the Christchurch suburbs of Aranui, St Martins, New Brighton, Wainono, Beckenham and Opawa – all areas whose plumbing systems were affected by the recent earthquake in the country.

Residents who sign up to take surveys will receive a series of text questions about the earthquake reconstruction efforts.

Director Adam Hutchinson (pictured) said: “The text message survey allows data to be captured from almost anywhere – in this instance, from the portable toilet on your street.”
