Days later Chris' two daughters wrote a condolence card for Ardern and Clarke Gayford, with his seven-year-old daughter writing she hoped Ardern wouldn't send her to prison.
Just months later Chris received a phone call from Ardern, who had received his daughters' heartfelt letters.
"It was none other than Jacinda and she basically rang up to say 'sorry you had to go through that, thank you for stopping by and thanks for the card'," Chris told Stuff.
"It was extremely nice of her to take time out of her day to check that I was okay for running over her cat."
While Ardern's phone call to Chris eased some of his guilt, he felt he needed to approach her in person.
A few months after the tragic incident, Chris confessed to Ardern in person.
After seeing her at the park with friends, Chris went up to her and told her he lived locally before apologising for killing Paddles.
"I told her I was aware of where she lived and I basically confessed that I was the one who ran over Paddles," he told Stuff.
"I said, 'I'm so sorry', and then she said, 'No, I'm sorry' and it kind of went round in circles."
To this day Chris still feels bad over the accident, saying it was a shock, especially given the popularity and social media following of Paddles.
