The Manurewa mother was still in hospital recovering from injuries last week.

A woman is warning others to be vigilant after she was repeatedly beaten before being tied up during a home invasion in south Auckland.

Two men forced their way into the Manurewa woman's home late on November 11 demanding cash and jewellery.

The woman, who asked to remain anonymous, is recovering in Middlemore Hospital after the violent incident.

She was home alone at 9.30pm on that Friday night. She heard a knock at the door.

Thinking it was her neighbour that regularly visits, she opened the door to be faced with two men.

"The bigger one pushed his way in and a second one behind him came in and closed the door.

"They were pushing me, hitting me on my head...asking me, 'give me the money, give me the jewels'."

At one point, she was knocked over and dragged a small distance. All the while she was continually hit and kicked in the head.

Then, she said the larger offender grabbed a "dagger-like knife" from his sock and held it to her throat.

"He said if I made any noise or screamed...'you know what we can do'."

She said she began to pass out while they tied her up and gagged her mouth.

A week after the ordeal, she was still suffering headaches and loss of vision. She says it was hard to move the left side of her body.

She's speaking out to warn others to be vigilant with strangers knocking on front doors.

Her daughter, who found her mother after returning home from work, said people should watch their surroundings - especially at night.

"Just be aware, be vigilant. This could happen to anybody. If you're at home alone, try and see who's at the door before opening it."

POLICE TO INVESTIGATE:

Police have yet to take a formal statement from the woman.

Head of Manurewa CIB, Detective Senior Sergeant Shaun Vickers said that at this stage, police can only describe the offenders as two males.

There are no indications on how they arrived and left the area at this point.

"But I would appeal to the public if they saw any suspicious behaviour around the Dr Pickering Avenue area at the time to get in touch."

Forensic examination of items of interest found are currently underway. Vickers wouldn't elaborate on what they were.

Police categorised the incident as an aggravated burglary and a kidnapping, something that's not common in the Manurewa area, Vickers said.
