Council officials have closed part of a main street in the South Island town of Fairlie because of what the say is a severe risk of asbestos contamination from a burnt out building.
The fish and chip shop on Riddle Street was extensively damaged on Monday and the Mackenzie District Council now says it contains asbestos.
It has closed a section of the street as well as a children's playground and the public toilets, and will start testing on Friday morning.
It would focus on areas around the nearby businesses and council staff were also wetting down shop fronts and the street to reduce the number of any airborne particles.
High winds on Thursday afternoon stirred up residue from the fire and more wind was forecast overnight.
The results of the tests would be known by later today or early Saturday.
