A man accused of killing a baby in Ngaruawahia has pleaded guilty to the girl's murder.
Matthew Shane Ellery made the admission at the High Court in Auckland on Friday.
Serenity Scott-Dinnington was injured in her Ngaruawahia home in Waikato in April 2011 and died from a head injury in Starship Hospital two days later.
Police have thanked members of the local community for their support during the long investigation.
They say that support played a significant part in getting justice for the six-month-old.
