There's a clone of the contest on our prog4fun server: https://prog4fun.csse.canterbury.ac.nz.
This is a public server that anyone can register on with any credentials.
Once registered they should enrol themselves in the "course" Programming Contest Problem Archive and they'll then be able to access the clone of NZPC-2022 here:
