Sale is also wanted on two arrest warrants and is facing charges of driving while disqualified.
The pair took off and have not been seen since.
A source said the pair are parents to a terminally ill child who is being treated in hospital.
"They've just left the child there," the source said.
"They've taken off... pretty much abandoned the child."
They have made no contact with the hospital since Selesele's brazen escape.
Detective Senior Sergeant Roger Small said the hunt for Selesele and Sale continued.
He could not comment on the specifics of the efforts to find them.
"Both Lusitino and Jacinta are believed to be using a white Holden Combo van, registration CYN814 and it's believed they are in the Waitakere area," Small said.
Selesele is described as a Pacific Island man, 1.82m, with a large build.
Sale is around 1.78m and of medium build.
A spokeswoman for the hospital where the child is being treated declined to comment.
