Police in Northland are reporting progress in their inquiry into the death of a baby in Kaitaia.
Maree Takuira Ngahere, who was less than four weeks old, died last month after suffering head and other injuries.
Investigators are speaking to a large number of people both in Northland and further afield as part of the investigation, Acting Detective Inspector Lloyd Schmid said.

The nature of the serious injuries inflicted on the baby was deeply concerning, Mr Schmid said.
"We know there are people out there who hold vital information about this case, and we urge them to come forward," Mr Schmid said.
A spokesperson for Maree's family, Bardia Matiu, said the family was united in their support for the police.
"We want to know what happened to our mokopuna," she said.
