Senior Constable Bruce Lamb and Constable Mitchel Alatalo were released from Christchurch Hospital this afternoon.
The men will continue to receive medical attention in the coming weeks. It's too early to say when they will return to duty, the police website reported.
Mr Lamb, a police dog handler, whose dog Gage was shot dead in the incident, was shot in the face and had titanium plates inserted in his face and jaw in surgery at Christchurch Hospital on Tuesday night. Mr Alatalo was shot in the thigh.
Canterbury police commander Superintendent Dave Cliff said both were recovering well, though still suffering the painful effects of significant injuries.
"It's great news that Bruce and Mitch are doing so well and it's a great relief for their families and friends, both in and outside of the police," he said.
"Bruce and Mitch are getting better by the day but they still have a painful recovery ahead of them. I know both of them are itching to get home and try and get some normality back into their lives. We will be continuing to support the men and their families throughout this process."
Mr Lamb had been called by two officers to Buccleugh Street address on Tuesday morning. The officers were looking for someone who had been released from psychiatric services and made threats to another person.
They could not find the person and were making inquiries at a neighbouring house when they smelt cannabis. The routine check turned violent after one man was arrested and the second ran inside the house.
Mr Lamb was shot in the face. Mr Alatalo attempted to escape through a window and was shot through the leg.
Police yesterday revealed that a Taser stun gun was used by police in the incident, but without success. Mr Lamb also had access to a firearm, but chose not to use it when entering the house because there were no immediate threats.
Mr Cliff said the events on Tuesday were fast moving and each day police are learning more about what took place.
"It's a testimony to the courage of Bruce and Mitch that even after they had been shot they continued to do everything possible to protect others from being hurt."
He said Mr Alatalo did not immediately realise the severity of his wound.
"Once he scrambled out of the house he was assisted by other staff. He donned ballistic body armour and a Bushmaster rifle which had been brought to the scene after the shooting. Mitch and others worked together to contain the scene and ensure there was no risk to anyone else.
"Despite being shot in the face Bruce too made it back to his van and radioed Comms. This meant help was quickly on the scene and that other staff knew that an armed response was required.
"Both men were reluctant to leave their roles but the severity of their injuries meant they needed to get to hospital as quickly as possible."
Mr Cliff said police still needed to formally interview the pair about what took place.
"It will be several days before they are well enough for this to happen."
Attempted murder charges were laid against 34-year-old Christchurch man, Christopher Graeme Smith yesterday. A man from the same Phillipstown address, 31-year-old unemployed Steven Paul Smith, was charged with possession of cannabis.
Both have been remanded in custody until July 28. Police will not confirm the pair are brothers.
