In March 2018, Gaze became the first New Zealander to win an elite UCI Mountain Bike World Cup title, when he claimed the cross country event in the first round of the season in Stellenbosch, South Africa. In April 2018, Gaze won the gold medal in the cross country event at the 2018 Commonwealth Games. Despite his win, Gaze came under significant media attention for his perceived unsportsmanlike behaviour towards his compatriot and silver place winner Cooper. Gaze was fined CHF200 by the International Cycling Union for showing Cooper the finger during the race.
