Two people have been charged after two Lower Hutt children, four and five-year-old siblings, suffered "horrific" injuries.
A man and woman, both 25, were charged on Wednesday and will face court on Thursday.
Detective Senior Sergeant Rebecca Cotton said the man has been charged with wounding with intent to cause grievous bodily harm, wilful ill treatment of a dog, attempting to pervert the course of justice, and selling and cultivating cannabis.
The woman is also facing two charges of failing to protect a child, two charges of attempting to pervert the course of justice and failure to carry out obligations in relation to computer search.
The charges follow two search warrants at different addresses in the Hutt Valley.
Police are not ruling out further charges.
The pair were held in custody overnight and will appear in Hutt Valley District Court on Thursday.
"We are elated to be able to share this news and recognise the genuine concern and outrage from the community that has gotten us here," Det Snr Sgt Cotton said.
"This result cannot be attributed to any one thing – a number of enquiries have taken place over the past week culminating in interviews with the two people that have been charged yesterday afternoon.
"Our priorities have been twofold - ensuring those responsible for the harm these two children have suffered are put before the court, and the ongoing welfare of these two siblings."
The siblings, who were hospitalised, are still recovering well. They remain in a safe place and are being cared for.
Police have previously said they believe the children were deliberately hurt "likely over a period of time".
Police ask anyone with information about the crime to contact 105, quoting file number 240308/4647. Information can be provided anonymously via Crime Stoppers on 0800 555 111.
