"I really, really loved it. What a way to end a marathon career," she said.
"It was by far the best event I've ever done. It wasn't like running a marathon, it was like a 26-mile-long party."
Mrs Hooson said since her stroke she did not cope well with crowds and loud noise, but the encouragement of two million spectators lining the streets helped her through the pain to the finish line.
"In my eyes I felt a personal connection with these strangers. They were calling out my name, high-fiving and encouraging me the whole way. When I finished I thought, 'I can't believe I've just run a marathon'. It was a party from go to whoa."
Her time of 7 hours, 40 minutes was affected by stopping for photos and dancing with every fireman, policeman and gospel singer she met.
She was accompanied by sister Rebecca Drage and guides Niva Retimanu and Pascale Biliau from Achilles, an organisation helping disabled people compete in mainstream sports events. Mrs Drage and Mrs Reti-manu also joined Mrs Hooson and her family in the Kerikeri Half Marathon on Saturday.
The New York event was emotional not just because it was her endurance running swansong but also because of the many other disabled runners they encountered.
"I had to concentrate not to burst out crying when we saw them," she said.
She was already thinking about new sporting challenges after her operation, possibly involving swimming or cycling. Mrs Hooson suffered a massive stroke after a freak waka ama accident in 2005.
She had to learn to walk and talk again and gradually returned to her pre-stroke sport of endurance running. When she arrived in New York to run the 2012 marathon she found the event cancelled and the city in chaos after a battering by one its most powerful hurricanes.
