Cyclone Season Begins: System Forming Near Pacific Could Hit NZ Before Christmas 2025

Early Alert for Kiwis as Cyclone Season Kicks Off

New Zealand is entering the 2025–26 cyclone season, and meteorologists are closely monitoring a tropical system developing near the South Pacific islands that could bring severe weather to the country before Christmas. Officials are urging residents, particularly in the North Island, to prepare for heavy rain, strong winds, and coastal hazards in the coming weeks.

For Whangārei resident Mark Te Rangi, the early warning is a wake-up call:

“We’ve seen what cyclones can do in the past. It’s good to know early so we can secure property and plan travel safely.”

Why Cyclone Season Is Important

• Cyclones in the South Pacific can rapidly intensify, sometimes within 24 hours.
• Even if a cyclone doesn’t make landfall, heavy rain and high seas can cause flooding and slips.
• The North Island, especially the Bay of Plenty, Auckland, and Northland, is most at risk from low-pressure systems tracking south.

Meteorologist Sophie Carmichael explains:

“The ocean is warmer than usual this year, which could feed stronger cyclones. Early preparation is crucial for communities and travellers alike.”

Current System Under Watch

• Location: Approximately 500–700 km northeast of Fiji, moving southwest.
• Status: Tropical disturbance expected to intensify into a tropical cyclone within 48–72 hours.
• Potential impact: Heavy rainfall, strong winds, rough seas, and localized flooding, particularly in coastal North Island areas.
• Timing: Could approach New Zealand in mid to late December, coinciding with peak holiday travel.

MetService and NIWA (National Institute of Water and Atmospheric Research) are coordinating closely to monitor the system’s path and intensity.

Expected Weather Impacts

Residents should be prepared for:

• Wind gusts exceeding 90–110 km/h in exposed areas
• Rainfall totals of 100–150 mm, leading to slips and urban flooding
• High surf and coastal erosion
• Potential power outages due to fallen trees or infrastructure damage
• Disruptions to air, sea, and road transport, especially in the North Island

Auckland Emergency Management reminded residents:

“Even if the cyclone weakens before reaching New Zealand, secondary impacts like flooding and strong winds can still be hazardous.”

Real Stories: Lessons From Previous Cyclones

Karen and Peter Ng, Auckland residents, recall Cyclone Gabrielle in 2023:

“We underestimated the rainfall and ended up trapped at home for a day. Now we make sure to check warnings early.”

For farmers and small businesses, cyclones can be financially challenging:

“Even a short spell of heavy rain damages crops and disrupts deliveries. Early notice helps us protect what we can,” said Bay of Plenty grower Tom Whitaker.

Preparation Tips for Residents

• Secure outdoor furniture, trampolines, and garden tools
• Check gutters and drains to prevent flooding
• Stock up on essentials: food, water, batteries, and medications
• Charge phones and power banks
• Develop a family emergency plan for shelter and evacuation
• Monitor MetService and NIWA alerts daily
• Avoid coastal areas and rivers during storm surge events

Authorities also recommend checking insurance coverage for cyclone-related damage before the season peaks.

Travel & Event Considerations

• Flights and ferries may face delays or cancellations if the system approaches.
• Road travel could be dangerous due to slips, fallen trees, or floodwater.
• Outdoor Christmas events may be postponed or relocated indoors.
• Holiday accommodation in vulnerable coastal areas should be booked with flexibility.

Transport analyst Claire Henson notes:

“Cyclones arriving close to Christmas could severely impact domestic travel plans. Bookings, itineraries, and logistics should be flexible.”
