The man police wanted to speak to in connection with the murder of Auckland homeless man Maqbool Hussain has been caught in Taupo.
Police released the name and photo of Justin Vance Turner, 28, as a "person of interest" four days ago.
Hussain, 49, was found dead at the back of a vacant grocery store in Balmoral on Monday last week, police said.
This afternoon, Turner - who had been sighted in the Wairarapa at the weekend - was seen by members of the public "acting suspiciously" near Taupo wharf.
They alerted police and officers made the arrest, a spokeswoman said.
Turner was previously described by police as "dangerous" and people were warned not to approach him.
Members of the Operation Gridley homicide investigation team would travel to Taupo today to interview Turner. It's not known how long he had been there or how he got there.
Detective Inspector Chris Cahill said locating Turner was a welcome breakthrough for his team. It had been working solidly since Hussain's body was found in his Balmoral sleepout.
"As with all such investigations, this is just another step in a process so we won't be slowing down but it is good to know that Mr Turner is in custody," Cahill said.
"We have a lot more work to do on the investigation so anyone who has information should share it with us."
It was not known when Turner would appear in court.
