Two vehicles crashed this afternoon on State Highway 1 north of Beach Road at Paekakariki, causing more than five hours of delays for peak-hour traffic in both directions.
Emergency services were called to the crash at about 2.45pm. Initial reports indicated that two people were injured.
The highway was closed after the crash. By 3.30 the lanes had been reopened in both directions, but the NZTA was reporting queues from Plimmerton to the Raumati straights.
At 4.30: northbound queues were back to Mana, with delays expected to reach Porirua. Southbound queues remain backed to the Raumati straights.
At 4.50, northbound queues were even longer – back to the Paremata roundabout. And the NZTA said the delays were “significant,” one of its most-used words these days.
Half an hour later, the first mention that traffic was at a standstill between Porirua and Paekakariki.
Please if possible continue to DELAY your journey north through SH1 #Paekākāriki  or expect SIGNIFICANT DELAYS. Traffic remains at a standstill northbound between Porirua and Paekākāriki. While southbound is still queued back to Raumati South. ^IF pic.twitter.com/emsukQgvPA

And at 6.50, four hours after the crash, there were continuing significant delays between Plimmerton and Paekākāriki, with queues back to the Plimmerton Roundabout. Northbound traffic was slow moving, due to vehicles merging from the Paekākāriki Hill Rd. Southbound delays remained back to Raumati South.
It wasn’t till after 8pm that normal traffic flows had resumed.
