A home that was the scene of a violent home invasion in the North Waikato town of Tuakau will remain cordoned off overnight.
A man found inside the home is now in intensive care.
The cordon surrounds the home on Jellicoe Avenue and part of a property next door. Windows are still open and on Sunday evening police officers were on guard outside.
The badly injured man was stabbed and suffered a head injury.
Police said it was too soon to say what the motive was for the attack.
Jellicoe Avenue runs off the centre of the township and is in a residential area.
