A large fire has broken out in the Auckland suburb of Glen Innes.

The fire was at the AHI Roofing plant on Felton Mathew Avenue and reportedly started around 11am.

Witness, Alan Parker, watched the building burst into flames.

"For a long time there was thick, black smoke and flames rising probably six metres up in the air, but now the Fire Brigade seem to have it under control. It's turned to white smoke, no flames."


Mr Parker says there's now a large contingent of firefighters on the site dampening down.
