Lance Corporal Pralli Durrer also didn't survive the firefight.
Doctors striving to stop the bleeding from bullet wounds that had shattered Private Taka's pelvis into 10 pieces nearly lost him twice on the operating table.
From Afghanistan, he was flown to Germany, where his wife joined him while he had medical treatment before being flown to Washington, where - in a rare move since the Vietnam War - the New Zealand Government organised a plane fitted for medical transfers to fly him home.
While spending three months in Burnham Hospital, he was joined by his parents, Christine and Joseph Taka, of Whangarei, whom the army arranged to stay with him while he was "learning to walk again". The army has also provided Private Taka with a house at the camp with wheelchair ramps.
He said a big breakthrough came about seven months ago when he received a spinal cord stimulator implant, which reduced the agonising pain he had been experiencing during his recovery.
He was particularly pleased the implant had enabled him to almost eliminate use of the painkillers OxyNorm and OxyContin - trade names for the prescription drug Oxycodone, dubbed "hillbilly heroin", which Whangarei addiction specialist Dr Alistair Dunn wants under tighter control in Northland.
"I suffer from a condition known as corsalga or chronic regional pain syndrome," Private Taka said.
"Nerves damaged in my spine send pain messages to my brain even though there is no longer injury present.
"But next month I'm heading for the United States with two other soldiers to compete in Marines Paralympics' shooting and wheelchair basketball events.
"I'm now 70 per cent back to normal."
Private Taka is still undergoing rehabilitation, but is now back on his feet, going to the gym, working on light duties and active with his wife and their three children.
