"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 being hit and kicked in the head.
She said the larger offender then 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.
A week after the ordeal, she was still suffering headaches and loss of vision. She said it was hard to move the left side of her body.
She spoke out to warn others to be vigilant with strangers knocking on front doors.
Head of Manurewa CIB, Detective Senior Sergeant Shaun Vickers said police could only describe the offenders as two males.
Police do not know how they arrived and left the area, he said.
He urged anyone who noticed any suspicious activity in the Dr Pickering Avenue area at the time to contact police immediately.
