Gosselin had only recently recovered from a leg injury she sustained in September which required surgery.
She said the sudden rush “sent me off my feet for a second”.
Gosselin said her boyfriend and former bodyguard Steve Neild was on the scene to assist supermarket staff and shoppers who gave chase.
“I love that Steve turns right back into a cop on a moment’s notice,” she said.
The 50-year-old mother-of-eight compared the quick response of staff and bystanders to what she’s observed back in the States.
“You should see all the Kiwi men running after him, trying to stop him. Everybody’s on their phone to the police. It’s a big deal here, because honestly, there’s not much crime here,” she said.
“In America, they would have just let him go.

“Often-times, [people] don’t pitch in and they don’t try to stop it. It’s so refreshing to see. There was like six or eight of them that went flying after him.”
Gosselin added that even she contributed to efforts to halt the thief in his tracks, kicking his shoe as he made a break for it, according to the Daily Mail.
She was also heard shouting “good job guys” as two New World staff returned the shopping trolley to the supermarket.
Gosselin reported the thief managed to escape in a waiting car, but not before several members of the public took down the vehicle’s number plate, which she said was “so cool”.

She was seen in a previous TikTok walking around the New World admiring New Zealand products such as Vogel bread and crumpets, exclaiming “America could never”.
Kate Plus 8 was a reality show about the Gosselin family: Kate, her estranged husband Jon and their eight children, fraternal twins and sextuplets.
The hit show enjoyed an 11-season run from 2007-2017.
Gosselin and her children travelled to New Zealand in 2011 to film an episode which featured visits to Ōtorohanga Kiwi House, Waitomo Caves and Rotorua.
She later called the trip a “nightmare” saying the group were mobbed by paparazzi in the King Country town of Ōtorohanga.
