President Lionel Aingimea confirmed the incident involving the nurses at the Meneñ Hotel quarantine residence during his weekly update.
The three nurses were part of a group of people who were repatriated from Fiji last Friday.
A day after arriving in quarantine, two nurses who were already on island visited three of their colleagues in quarantine.
They met at the back of the quarantine facility where it is single fenced and made contact through the fencing.
