UPDATED: The Boulevard in Papamoa is open for traffic again after being closed while firefighters dealt with a minor chemical spill.

About 16 litres spilled near one of the roundabouts. The road was closed about 12.20pm and reopened sometime after 2pm.

'It was some sort of acid,” says NZ Fire Service northern communication centre shift manager Scott Osmond.

'It was supposed to be an acid of some sort but it was all watered down, and we ended up watering it down even more. The BOP people were there and they told us what to do, so it was all good.”
