The stand-off with police began just before 10am on Friday when three police staff, accompanied by a police dog, visited a property in Kokiri Cres, Porirua, seeking Mr Tekira who was wanted for arrest.
Police said Mr Tekira had brandished a firearm and shot and killed the police dog. The dog's body was immediately removed from the house by two officers, and the third was injured after jumping from a second storey window.
Police staff, including the Armed Offenders Squad, began searching for Mr Tekira who left the residential property and was reported to be armed.
A stand-off ensued when Mr Tekira was located at another house on the same street. Police negotiated with him and deployed a number of tactical options overnight in order to gain access to the house, including gas canisters. Police said there had been no shots fired by their staff.
In a press conference on Saturday, Wellington District Commander Sam Hoyle said police had entered the house about 11am that day, and using a remote camera could confirm Mr Tekira was alone in a room on the upper level of the house where a shotgun was present.
"This is not the outcome that we wanted," he said. "Our negotiators worked tirelessly throughout the night in an attempt to get a peaceful ending to this event. Unfortunately that didn't occur."
