Upokongaro School pupils of the future will have a good understanding of the impacts of Covid-19 and how their school managed remote learning thanks to letters from the past.
When a time capsule is excavated in 2045 children at the riverside school north of Whanganui will discover how pupils of 2020 and their families live and learn.
The school which opened in 1870 celebrated 150 years of primary education on March 14 just a week before New Zealand entered level 4 lockdown and principal Warren Brown said it was a brilliant weekend of celebrations.
"We didn't get to bury a new time capsule straight after as we planned to," he said.
"The one we lifted at the 150th celebrations was buried after the school's 125th anniversary in 1995 and some of the things in there made us feel a bit sad."
