Zavarzina opened the 2017/18 season with a promising fourth-place finish in the first race of the season in Carezza, but she had a poor run of results in the following World Cup races. She reached her first podium of the season in Rogla in the parallel giant slalom race through the end of January. She backed that up with another fourth-place finish in the same discipline in Bansko, the last World Cup stage before the Olympic Games.
