NZTA Road Closures Map: How to Check Real-Time Status (2025)

You’re about to drive across New Zealand, and the first thing you check is whether the road ahead is open. State highways close without warning—snow, slips, crashes, or planned roadworks can turn a four-hour trip into an all-day detour. The official NZTA Journey Planner map gives you real-time closure data straight from the agency that manages the network, and this guide shows you exactly how to use it, what each symbol means, and where the map falls short.

State highways in New Zealand: ~11,000 km ·
Active road closures (typical daily average): 30–80 ·
NZTA Journey Planner daily visits: 500,000+ ·
Official road status update frequency: Real-time / 5-minute refresh

Six key facts about the NZTA road closures map, one pattern: the official tool is powerful for state highways but leaves local roads to other agencies.

How can I check for NZ road closures?

Using the NZTA Journey Planner homepage

1. Navigate to journeys.nzta.govt.nz – the central travel planning site from NZTA (national transport authority).
2. Click “Highway conditions” in the top menu to open the live map.
3. No login or registration required – the map is free for everyone.

The homepage directly displays the NZTA Highway conditions page, which NZTA describes as “the central place to find road closures, incidents, roadworks, and traffic cameras across New Zealand.”

Entering your start and end points

• Use the “Journey Planner” tab to enter a start and destination – NZTA’s planner shows travel time, cameras, delays, roadworks, and closures.
• Route suggestions are “indicative only” and may be unsuitable during closures – NZTA warns you to verify conditions on the map.
• If your journey includes local roads, NZTA says you should “refer to your local or regional council for closures or unplanned events.”

The implication: the Journey Planner is a great starting point, but it’s not a guarantee – always double-check the highway conditions layer before setting off.

Reading the highway conditions layer

• Red road markers = road closed to all traffic.
• Orange markers = incident or hazard (e.g., crash, debris, flooding).
• Green markers = normal conditions with possible delays.
• Click any marker for details: cause, expected duration, and alternative routes.

These colours are consistent across the NZTA map and are the same on the regional dashboards. The pattern: red means stop, orange means caution, green means go – but always check the pop-up for the full story.

Which roads are closed in New Zealand today?

State highway closures by region

• NZTA provides regional dashboards for Auckland, Wellington, Otago, West Coast, and more – each updated independently.
• The Traffic bulletins page publishes statewide summaries, such as the 13 July 2025 bulletin that reported SH6 reopening between Belgrove and Kohatu while other closures remained in the Top of the South.
• For a quick overview, use the “Traffic bulletins” filter – it lists all active bulletins by region and date.

What this means: the map is regionalised. If you’re travelling across the South Island, check both the Otago and Canterbury dashboards – a closure near the border might only appear on one.

North Island vs South Island closures

• North Island hotspots: SH1 Auckland-Wellington corridor, SH2 Wairarapa (Rimutaka Hill), SH25 Coromandel Peninsula, SH5 Napier-Taupo.
• South Island hotspots: SH1 Christchurch-Picton coastal section, SH7 Lewis Pass, SH1 Kaikoura coast, SH6 West Coast.
• Winter snow and ice close alpine passes regularly – check SH7, SH73 (Arthur’s Pass), and SH94 (Milford Road) on the map.

For the most current status, NZTA’s My Journeys alert service lets you save a route and receive email alerts during your selected days and times when there is a “significant hold-up or need for caution.” You can also set regional alerts for all state highways in a chosen region.

The implication: drivers who rely only on the national view may miss region-specific closures. The dashboard for your destination region is the definitive source.

Are there any road closures in Wairarapa today?

• SH2 through Wairarapa: The Rimutaka Hill section is prone to weather closures and incidents – check the NZTA map for real-time status between Upper Hutt and Masterton.
• Closures near Carterton, Greytown, and Featherston are typically shown on the state highway layer, but local roads in those towns are managed by the South Wairarapa District Council.
• The NZTA Wellington regional dashboard provides the most detailed view for SH2 through the region.

What this means: the Rimutaka Hill road is the most frequently closed state highway in Wairarapa. Check the map before any cross-region trip, especially during winter storms or after heavy rain.

What are the current road closures in the Coromandel region?

Coromandel state highway status

• SH25 and SH25A are the key routes around the Coromandel Peninsula – both appear on the NZTA map with real-time status.
• SH25A has been closed for extended periods due to slips and repair work – check the map for the current colour.
• During Cyclone Gabrielle (Feb 2023), SH25 and SH25A were both closed for weeks; the NZTA map was the primary source of updates.

The trade-off: the NZTA map is excellent for SH25 and SH25A, but local roads within the Coromandel townships (e.g., Thames, Whitianga) are not shown – you’ll need the Thames-Coromandel District Council website for those.

Local road alerts for Coromandel

• Council-managed roads like the popular scenic route to Cathedral Cove are not on the NZTA map.
• For Coromandel local roads, check the council’s emergency management page or Facebook feed.
• NZTA’s regional NZTA Waikato Facebook page sometimes posts joint updates for state and local roads.

The catch: no single source covers all Coromandel roads. Use the NZTA map for state highways and the council site for local roads – and allow extra time because conditions can change rapidly.

Is the road from Christchurch to Picton open?

Route 1: Christchurch to Picton (SH1 / SH7)

• SH1 north of Christchurch via the Kaikoura coast is the direct route, but it’s prone to slips and weather closures – check the NZTA map before leaving.
• SH1 south of Kaikoura was closed for weeks after the 2016 earthquake and remains vulnerable; the map shows the current status.
• An alternative is SH7 via Lewis Pass (from Christchurch to Springs Junction, then north to Picton).

Each route has its own closure history. A July 2025 NZTA bulletin noted that SH6 (nearby) reopened after slips, but SH1 remaining open was subject to daily checks. The pattern: the coastal route is the most scenic but the most unreliable in winter.

Route 2: Inland via SH7

• SH7 Lewis Pass is a higher-altitude route that can close due to snow and ice.
• The NZTA map shows both routes simultaneously – you can compare colours at a glance.
• My Journeys alerts can be set for both SH1 and SH7, so you’ll know before you leave which one is open.

The implication: for Christchurch–Picton travellers, the NZTA map is the best tool for route selection, but ferry conditions require a separate check.

Is the road to Kaikoura open?

• SH1 along the Kaikoura coast: This section is prone to slips and weather closures, especially during winter storms – the NZTA map shows the current status in real time.
• Inland alternative routes via SH7 or SH70 exist but add significant travel time and can also close in snow conditions.
• Check the NZTA map before traveling – the red/green marker system gives an immediate verdict on the Kaikoura coast road.

Why is the Auckland motorway closed?

Common causes of Auckland motorway closures

• Incidents: crashes, breakdowns, and debris are the most frequent – the NZTA map shows them as orange markers with details.
• Roadworks: planned closures for maintenance and construction are listed in advance under the “Roadworks” layer.
• Weather: heavy rain can cause flooding on the Southern Motorway (SH1) and Northwestern Motorway (SH16).

The Auckland traffic dashboard aggregates all closures, incidents, and roadworks for the region – it’s the most detailed local view. NZTA also runs the NZTA Auckland Facebook page which posts real-time updates.

How to check Auckland-specific traffic events

• On the map, select the “Incidents” layer to filter by crashes, hazards, or roadworks.
• Click any orange marker to see the cause, lanes affected, and estimated clear time.
• For planned roadworks, check the “Roadworks” layer – times and dates are listed.

The implication: the vast majority of Auckland motorway closures are short-lived (under an hour), but a single crash on the Harbour Bridge can snarl traffic for 10 km. The map gives you the detail you need to decide whether to wait or take an alternative route like the Western Ring Route (SH20/SH16).

Timeline: When New Zealand’s state highways close most often

• Typical winter storm: State highways close across the South Island due to snow and ice – SH7, SH73, and SH94 are most vulnerable.
• Cyclone Gabrielle (Feb 2023): Massive road closures across the North Island, many lasting weeks – the NZTA map was the only real-time source.
• Daily peak incident period: More closures reported between 7–9 AM and 4–6 PM, when commuter traffic is heaviest.
• Public holidays (Easter, Christmas): Increased roadworks and planned closures – NZTA publishes schedules weeks in advance.

The pattern: seasonal weather and human behaviour drive the closure cycle. Winter storms are predictable; summer holiday roadworks are planned. The map’s 5-minute refresh means you never have to rely on yesterday’s news.

What the NZTA map confirms – and what remains unclear

What NZTA says about its own map

“Our website gives you up-to-date information on road closures and delays.”

— NZTA Traffic and travel information page

“To navigate the map with touch gestures double-tap and hold your finger on the map, then drag.”

— NZTA Journey Planner instructions

“Route suggestions are indicative only and may be unsuitable if there are closures or unplanned events on state highways.”

— NZTA Journey Planner important notice

“If your journey includes local roads, you should refer to your local or regional council for closures or unplanned events.”

— NZTA Journey Planner local roads disclaimer

The NZTA Journey Planner map is the most reliable source for state highway closures in New Zealand, but it’s not a magic bullet. It covers all 11,000 km of state roads, updates every five minutes, and offers alerts through My Journeys. But it deliberately excludes local roads, private roads, and off-highway routes – those are managed by councils and other agencies. For New Zealand drivers, the choice is clear: use the NZTA map as your first check, supplement it with council websites for local roads, and sign up for My Journeys alerts to avoid surprises. On a winter morning, that five-minute check could save you a two-hour detour.
