Roadblocks have been set up around Auckland to prevent non-essential travel from the region until Wednesday, following the three new confirmed Covid-19 cases in the community, Stuff reports. The border took effect at 11.59pm Sunday, when Alert Level 3 came into force. Police warn the public that anyone who tries to leave or enter without valid reason should expect to be stopped. Eight checkpoints on the outskirts of Auckland will be patrolled and vehicles will be stopped and drivers questioned to prevent non-essential movement through the region.
