Level 2 Covid restrictions will be observed on the Marae as a precautionary measure to protect kaumatua and the immune compromised.
It will be televised by Māori Television and live-streamed via the internet to include those who would like to observe the anniversary.
A public event supported by Whakatāne District Council will take place on the same day at the Mataatua Reserve from 11.30am.
This is open to anyone who would like to pay their respects to the lost and injured as well as take time to reflect. A large screen will livestream the ceremony happening inside the Wharenui from 1pm.
Anyone attending is encouraged to bring their own refreshments, but not alcohol.
Organisations and community groups are encouraged to gather in whanaungatanga in their own 'hubs' to view the broadcast.
Ngāti Awa plan to host a larger and more inclusive event at a future date when international borders are open and affected overseas families will be able to join.
More information and updates on the event and locations will be available later this month.
