Guido Pella beat Nicolas Jarry 6-4, 6-3 and Diego Schwartzman defeated Cristian Garin 6-2, 6-2, to give the 2016 champions the opening win in Group C.
The teams are playing only two singles and a doubles in each tie, with the group winners advancing to the knockout stage.
Kazakhstan was leading the Netherlands after Mikhail Kukushkin beat Botic van de Zanschulp 6-2, 6-2.

The new Davis Cup is being played in World Cup-style with all 18 teams playing in a single venue in the same week.
