An 82-year-old Wainuiomata man was attacked with a wooden baton by two teenagers inside his home last night.
Hutt Valley police are now investigating the "cowardly" assault.
Detective Sergeant Mike Sears of the Hutt Valley CIB said the the Norfolk Street resident answered a knock at his door shortly before 8pm last night.
"He was confronted by two young males, who asked to speak to a person known to the victim. He was then pushed to the ground and struck over the head with a wooden baton. Demands were made for cash."
He said the offenders then made a "messy" search of the house, before leaving with an undisclosed amount of cash.
"We need the public's help in identifying these cowardly thugs. This victim was targeted in his own home.
"He has sustained bad bruising to his face and body and has been shaken by this attack and is currently staying with family."
Mr Sears said the offenders were 15 or 16-year-old males.
He said police were making positive progress, but described the wanted teens as "dangerous offenders".
"We want them caught as soon as possible. We urge anyone with any information to contact us as soon as possible on Hutt Valley Police on (04) 560 2600 or phone Crimestoppers on 0800 555 111."
