On 28 January 2018, Robinson was selected to the New Zealand team for the PyeongChang 2018 Olympic Winter Games, alongside alpine racers Adam Barwood and Willis Feasey. She became New Zealand's youngest-ever Winter Olympian, at 16 years and 70 days when the games began. At the Olympics, Robinson was coached by former alpine Olympians Tim Cafe and Ben Griffin. She finished 35th (of 81) in the giant slalom, the best result for a New Zealander in giant slalom at the Olympics in 38 years, since Fiona Johnson and Anna Archibald were 30th and 32nd in 1980 at Lake Placid, New York. She failed to finish the first run of the slalom event.
