According to posters on the page, the congestion is heavy from the Orewa off-ramp all the way through to Warkworth.
Facebook user Megan-Rose Sims posted video of the banked up traffic while heading south in the opposite direction, writing "tunnels backed up just before Orewa off-ramp - avoid like the plague".
Shannelle Rose wrote under a separate post that she hoped "everyone went to the bathroom" before getting stuck in the jam, while Ashleigh May Innes posed a "serious question".
"Is there like a secret back road for locals to get to and from Warkworth from Wellsford?" she said.
The NZ Transport Agency's Easter Journey Planner website is expecting northbound traffic on SH1, between Puhoi and Wellsford, to remain at its heaviest up until 6pm tonight.
