A new report on the Havelock North based Te Mata Mushrooms suggests a 600-metre odour buffer zone, a move that places the proposed kura kaupapa in the zone.
The zone has been recommended by Tonkin and Taylor, in a report commissioned by Hastings District Council, to assess the recommended separation distances between Te Mata Mushrooms and bordering development or "operational areas".
The report comes when debate rages in the community about whether or not this is the right place for the educational facility.
Hastings Mayor Lawrence Yule said it does not mean people cannot build within the buffer zone, just that best practice says it wouldn't be optimum to put residential housing there.
"And my interpretation of that would be [building] a school as well within 600m of a mushroom farm. You are just effectively inviting problems and conflict between the two types of use," he said.
