His story has been featured on international media including CNN and the BBC.
He told The Project that Friday March 15th was a turning point.
"For me everything changed on that day. I just thought if those things are still in the country, there is a chance that could happen again," he said.
While Kiwis were quick to applaud him, not all feedback was good.
"The first day I got lots of feedback from Kiwis, so that was nice."
"But when America woke up, I ended up with a deluge of responses from American gun enthusiasts."
He said there were literally tens of thousands of messages, tweets and Facebook comments.
After a call from the Washington Post who wanted him to do an opinion piece, he said the whole cycle has started again.
"They were keen to do a piece from me on New Zealand gun culture versus American gun culture."
John Hart said after his experience with the American gun lobby, he is keen to make sure they don't dominate the conversation.
"My message to the Government is don't lose your nerve, lets keeping following through on what we need to do. Let's talk to the experts and let's do it right."
