Two men will be appearing in the Christchurch District Court tomorrow charged with the murder of Bradley Lomax.
Police are not looking for anyone else in connection with the murder, said Detective Inspector Greg Murton.
Inquiries are continuing, with scene guards remaining at an address in Rangiora and one in Oxford overnight.
"I would like to thank all those people and members of the public who have come forward with information about the murder, and encourage others who have any information to make contact with the police," said Murton.
Information can be passed to Christchurch Police on (03) 363 7400. Alternatively, information can be given anonymously to Crimestoppers on 0800 555 111.
