A man has been charged with murder after a woman was found dead and a baby critically injured at a Matamata house on Monday.
Emergency services were called to the house on State Highway 27 at 1pm on Christmas Eve. Police said then that a man at the property, who was known to the woman, was taken into custody.
The baby who was found injured at the address remains in Waikato Hospital in a critical condition.
The 40-year-old man charged with murder will will appear in Hamilton District Court on Wednesday.
A neighbour believed the property was being rented by a brother and sister.
"We have seen her pushing a pushchair with the baby in it down the driveway," they told Stuff.
"They haven't been living there very long, a couple of months."
