Exactly what happened at the house is not yet clear; only that the bodies of a man and a woman were found after police were called just before 10am.
Police would only say it was a "tragic event" and that they were working to piece together what had happened.

Detective Inspector Colin Higson, of the Counties Manukau Police, said they believed the two adults were known to each other and they were not looking for anyone else.
The adults' relationship to the child is not yet known.
Shocked neighbours yesterday gathered outside the house to talk and comfort each other, as police officers stood guard and workedin the background.
Residents told the Herald the victims had been home last week and remembered the boy, whom they described as "full-on" - playing outside with toys he had received for Christmas.
