A police investigation into the savage mauling of a young Japanese girl by four dogs in the Bay of Plenty has been completed.
Sakurako Uehara was bitten more than 100 times by Staffordshire Bull Terrier crosses at a family friend's home in Murupara on 3 March.
The seven-year-old remains in a serious but stable condition in Middlemore Hospital and will need years of medical treatment and surgery.
The officer charged with looking into the attack, Detective Sergeant John Wilson, said on Wednesday as the investigation now complete, police are considering whether to lay charges against the dogs' owners.
The Whakatane District Council, which covers the Murupara area, said it is not pursuing any charges against the owners under its bylaws.
The dogs that attacked Sakurako Uehara were put down immediately after the attack.
