Ms Ellwood played the character Mandy Timmins on Shortland Street in 2006.
The pair were known to each other, and police are not looking for anyone else in relation to the incident.
The matter will be referred to the coroner after a police investigation has concluded.
A friend and former colleague who worked as a make-up artist with Ms Ellwood described her as "a beautiful soul who would do anything for anyone".
"She was always buying little treats for people - just so generous and lovely," the friend told Newshub.
"I'm just absolutely shocked and devastated for her family."
Police want to hear from anyone who had contact with the pair after 11am on Wednesday February 28.
