NZSO Interim Chief Executive Peter Biggs said the Orchestra's number one priority is the health and safety of its audiences players, staff and performing partners.
Most NZSO concerts have audiences of well over 500 people.
"The NZSO has been keeping a close eye every day on developments regarding COVID-19 and at every step following guidelines issued by the Ministry of Health.
"We will be rigorously following the Government's directive until it is lifted.
The NZSO is looking at including more live broadcasts of concerts and live streaming some performances on multiple platforms working with their strategic partner RNZ to make it happen.
NZSO subscribers will be contacted to discuss ticket options. All other ticket holders should contact the ticketing agency from where they purchased their tickets.
