Yelling at the gunman, the father of four hurled an eftpos machine and ran towards him, dodging bullets and ducking behind parked cars.
Brandishing a discarded rifle, Aziz made himself a target by shouting provocations, then chased the terrorist to his car, smashed a window and ran after him as he took off down the road.
His selflessness during the 2019 massacre that left 51 people dead has been recognized with the country's highest honor for civilian bravery, the New Zealand Cross.
Aziz said he did not hesitate to chase the "coward" away.
"I was worried about all the brothers and sisters we had inside. I was more scared for them than for myself. I had no fear of him," he said.
Governor-General Dame Cindy Kiro presented the award to Aziz at a ceremony at the Christchurch Town Hall, along with eight others who risked their lives in acts of great bravery.
Dr Naeem Rashid, who was shot and killed after charging at the gunman at the Al Noor mosque, was posthumously awarded the New Zealand Cross.
Rashid ran at the terrorist, diverting his attention from people trying to escape through a broken window on the other side of the room, helping at least seven to flee.
His son Abdullah Naeem said he was proud of his father.
"He was someone who stood up for what was right, he was someone who cared for other people. It shows how selfless he is, for the greater good of humanity," he said.
"It's really hard to find my way around the world without him, but I know he's still there, he's still watching me. He leaves a great legacy."
Senior Constables Scott Carmody and Jim Manning received the New Zealand Bravery Decoration for their exceptional courage in arresting the terrorist, by ramming his car.
The men did not want to speak publicly, but police commissioner Andrew Coster said the officers made a great judgment call about the gunman's escape route.
"They're not the kind of characters who would call themselves heroes. They're very reluctant to be recognized, they would say it's what any cop would have done, but we recognise the incredible courage they showed," he said.
Other people who drove past the Al Noor mosque and stopped to help were also recognized, including Liam Beale who received the New Zealand Bravery Decoration.
The search and rescue volunteer put his own life at risk by giving the wounded first aid and moving them to safety, all while the gunman was on the loose.
Wayne Maley helped the injured and dying outside the mosque, including a man shot in the hip and shoulder.
He still dreams about that day, waking back at the scene.
"Blood was coming through my fingers. I actually took my work vest off and made a little pillow for him and put it under his head, just to make it a bit more comfortable. His phone rang in his pocket, so I managed to pull it out of his pocket and put it up to his ear so he could talk, just to help him out," he said.
"Hopefully there are a lot of other Kiwi blokes like me who would do the same thing."
Lance Bradford, Mike Robinson and Mark Miller, who was killed in a crash near Cromwell earlier this year, also received the New Zealand Bravery Medal for their efforts helping the victims.
Dame Cindy Kiro told the men they showed great presence of mind and extraordinary courage, acting without hesitation to save the lives of others.
"The dreadful events of the 15th of March are imprinted in the memory of our nation and will be remembered also in many parts of the world. Measured against the stories of terrible personal loss are also stories of resilience, compassion and faith," she said.
"I take this opportunity to salute you in your bravery and to express our sincerest gratitude and respect, and assure you that your efforts will not be forgotten."
