A suspected chemical explosion has injured one person in Auckland tonight.

Emergency Services are at a Royalty Rise property in Red Beach, where there were reports of a chemical explosion involving chlorine.

One person is "moderately injured", the Fire Service says.

"This is a reaction involving pool chemicals", Fire Service spokesman Jaron Phillips said.


"The caller into us did say there was an explosion. It has generated fumes."

The 111 call was made about 6.20pm and four fire units are at the scene, including a hazardous materials team.

A "safe forward point" for emergency service workers has been set up at the corner of Royalty Rise and Albert Hall Drive.
