The NZ Transport Agency is urging holiday motorists to plan for delays as major state highway works and temporary lane closures roll out across Waikato and the Bay of Plenty.

A Christmas moratorium on roadworks will also begin today, but several high‑impact traffic restrictions remain in place for key summer routes.

As in previous years, the passing lanes on State Highway 2, between Pōkeno and the SH25 Mangatarata roundabout, will be closed during peak times to ensure smoother traffic flows.

The eastbound passing lanes will be closed on Saturday, December 27, and Sunday, December 28, between 4am and 10pm.

Westbound lanes will be closed on Saturday, January 3, and Sunday, January 4, between 4am and 10pm.

“Queues might be a little longer when the passing lanes are closed, but there will be minimal impact on your journey time,” said the agency’s Waikato journey manager, Andrew Brosnan.

“A slightly slower speed doesn’t make for a longer journey overall, as traffic moves more steadily.”

As SH2 is the main connection between Auckland and the holiday hotspots of the Coromandel Peninsula, Waihī Beach and Tauranga, Brosnan says it’s all about making the state highways safer for everybody.

“The Christmas shutdown for roadworks will be in place from midday Friday, December 19, and continue through to midnight Sunday, January 4. The break ensures fewer delays for travellers and gives our hardworking crews a chance to wind down and prepare for a busy start to 2026.

“Even though major work is put on hold, there may be sites under traffic management to keep road users safe.”

In the Waikato, the busiest spots are expected to be on SH25 around Tairua township, on SH1 between Tīrau and Karāpiro and on SH2 between Pōkeno and Matamata.

In the Bay of Plenty, the busiest spots are likely to be on SH2 between Paeroa and Waihī, on SH2 between Tauranga and Katikati and on State Highway 29 over the Kaimai Range.

Busiest Bay of Plenty corridors identified

The transport agency (NZTA) expects congestion at several well‑travelled routes in the region, with pressure likely on:

SH2 between Paeroa and Waihī

SH2 between Tauranga and Katikati

SH29 over the Kaimai Range

These corridors traditionally serve as main gateways for holidaymakers heading into and through the Bay of Plenty.

To help ease the flow of traffic, NZTA will also implement passing‑lane closures on SH2 during peak days, aligning with wider summer management across Waikato and the Bay. While queues may form, officials note journey times should not significantly increase, as slowing speeds often stabilise overall traffic movement.

Christmas Works Moratorium

A region‑wide moratorium on major roadworks begins midday Friday, December 19, and will run until midnight Sunday, January 4.

This annual pause gives road crews a well‑earned break while reducing disruption for travellers.

Although heavy construction stops, some sites will still have temporary traffic management in place for safety.
