Visits by international students to Whanganui High School have been cancelled amid the coronavirus outbreak and subsequent travel restrictions.
Whanganui High School principal, Martin McAllen, said it was the best move considering the circumstances.
A visit from 18 Thai students and two accompanying adults for a six-week exchange was cancelled last week and more visits are expected to be.
"The school felt it was wise to cancel the trip at the earliest opportunity to minimise the risk to students and the community," McAllen said.
The group of 20 was scheduled to be in Whanganui from the March 25 until May 5 for a study tour during school holidays in Thailand.
