Residents of Waipu in Northland are being warned to stay indoors after a major fire in the town centre put residents at risk of inhaling asbestos.

Ten fire crews were still on site at 7am this morning after being called to the well-involved building fire, 60m x 20m, at 1.20am at the Waipu Cafe and Deli on Cove Rd.

"We currently have 10 crews still in attendance dealing with that fire, we are asking people to avoid the main street as there is a possible risk of asbestos and everyone is asked to avoid the smoke and close windows," a Fire and Emergency New Zealand spokesman said.

"There is also a power outage as result of this."

The Centre, Cove Rd, is closed between Nova Scotia Dr and St Marys Rd.

Waipu Pharmacy, next door to Waipu Cafe and Deli, reported it sustained "extensive damage" because of the fire.

"Thankfully nobody has been hurt. Waipu Deli-Cafe and Harkers Herbal have also lost their businesses.

"We will work hard to get services back up and running ASAP, and will keep the community posted via Facebook as to how you can receive services," the business posted to Facebook.

Pharmacist Brenda Wells said the community would feel the temporary loss of the pharmacy as it was an essential service to the rural community.

She told Newstalk ZB she heard the news at 3am when a staff member called her to tell her the building was burning down.

The damage to the store was significant and she did not expect anything in the building to be salvageable.

"Very devastated. My initial concerns is getting the pharmacy services for the community back up and running, that's what I'll be focusing on, we will need to find a temporary premises.

"Get it set up so people can get their medicines back as soon as possible."

She was in Christchurch for the weekend and is flying back to the North Island today.

The next closest pharmacy in Ruakaka would fill in for her pharmacy until it was back on its feet, she said.

She had been operating the pharmacy for the past six years.

Waipu Hammer Hardware posted to Facebook that three businesses, Harker Herbals, Waipu Cafe and Deli and Waipu Pharmacy, had been "burned to the ground".
