Police attempting to arrest a woman in Hokio Beach, near Levin, ended up trying to rescue the woman from a burning home.
The incident began at 7.45am this morning after police officers arrived at the 40-year-old woman's house with a warrant to arrest her.
Police allege she refused to let officers in and only spoke to them from behind a closed door.
Sergeant Martin Bull of the Levin police said the woman had displayed some "concerning behaviour'' when the officers went to the house, and had an iron bar in her hand.
"The officers were genuinely concerned for her safety and well-being and tried to communicate further with her,'' he said.
