A man has been taken into custody after a "family harm incident" that turned into a billowing blaze in Whangarei.
Emergency services were called to a property on Maunu Rd about 6.30pm.
Police told the Herald they were initially called to a family harm incident where a woman had been kept hostage.
"When police got to the scene the property was on fire. Reports of a woman being kept hostage were inaccurate," a police spokeswoman said.
Police were speaking to the man and other people who were at the property to establish what happened.
