A plan for stricter standards for seasonal worker accommodation in Marlborough is set to be adopted by the region's district council.
About 3500 workers arrive in Marlborough each year, mostly to work in vineyards. A report commissioned by the council found that much of their housing is over-crowded, and that for every seven residents there was only one toilet.
Only one in five of the houses inspected was not overcrowded.
Marlborough mayor Alistair Sowman says a bylaw is being considered to set minimum standards. The council will also consider allowing more worker accommodation to be built in rural areas.
