The 16-year-old who died after a shooting in the Christchurch suburb of Casebrook is being remembered by family as a "kind, talented and deeply loyal" young man.
Det Snr Sgt Nicola Reeves says four arrests have now been made over the death of Connor Whitehead, who was found dead at the Casebrook house on Friday. One was charged on Saturday night and three more were arrested on Sunday.
A statement was released by Whitehead's family on Monday morning.
"We are devastated by Connor's death and still trying to come to terms with what has occurred," the statement said. "We are in shock and want answers about what happened to our beloved son, brother and friend. The magnitude of this senseless loss hasn't begun to sink in.
"Connor was in no way connected to or affiliated with the people who are responsible for his death."
The family said they were grateful for the love and support they've received.
"Connor was dearly loved and his passing has left a huge hole in our lives. He was a kind, talented and deeply loyal young man who had such a bright future ahead of him.
"We would like to thank emergency services for their response on Friday night and their ongoing support."
Reeves said an investigation into the shooting is ongoing.
"A 32-year-old man was arrested at a Burnside residential address last night following the execution of a search warrant," she said on Monday morning.
"Two women, aged 36 and 43, have been arrested and charged with accessory after the fact to murder. They will appear in the Christchurch District Court today.
"The 46-year-old man arrested on Saturday night is also due to appear today facing one charge of accessory after the fact to murder."
One person was still being sought in relation to Connor's death, Reeves said.
"That person is aware they are being sought and we encourage them to come forward and speak with police."
