"This, alongside taking into consideration the situation our fellow Aucklanders are currently in, led to the decision to postpone to September 11, and, overall, feels like the right thing to do," O'Connor said.
She said these were challenging times for everyone, but she was confident "we will get through this together".
"We are committed to delivering a safe event for our participants, and the team is excited to go live with the event on September 11, and we will remain flexible to the situation come this time.
"The New Zealand Masters Games has over 30 years' experience as a significant event on the New Zealand calendar, flexibility and connection are bywords of the event and we remain confident moving forward."
The Masters Games are set to take place from February 5 to 14.
