Firefighters are battling a blaze near Auckland Airport after several batteries caught fire.

Three fire engines are at the scene on Airpark Drive and firefighters have been seen entering a warehouse directly adjacent to a Rocket Lab office.

A witness told Newshub the warehouse is also owned by Rocket Lab, however a Rocket Lab spokesperson has repeatedly refused to comment on whether it's their warehouse.

However the spokesperson did confirmed the blaze is near the Mission Control office, which is their base of operations in Auckland.
