Cyclone Vaianu: How to prepare your home and grab bag for when the storm hits NZ

North Islanders are being told to get sorted now, with Tropical Cyclone Vaianu set to bring severe gales and heavy rain this weekend.

According to MetService, there are already 18 weather watch warnings in place across the North Island, and depending on the cyclone’s path, it could turn into a “multi-hazard, potentially life-threatening” event.

The combination of damaging winds that could reach over 120kph, heavy rain, and coastal flooding as the system moves closer makes it particularly important for the Island’s isolated communities to have a plan in place to act quickly if necessary.

Prime Minister Christopher Luxon is urging Kiwis in the North to “stock up, get supplies and tie things down.”

As always, it’s better to be safe than sorry, so having a plan in place is essential.

Advice to prepare for Cyclone Vaianu ahead of the weekend:

What you should do now

• Clear drains and gutters to avoid flooding

• Tie down or bring in outdoor furniture (including trampolines)

• Remove any debris or loose items from around your property

• Charge your devices and power banks

• Make a plan with whānau in case you need to leave quickly

A sample grab bag checklist could include:

• Water (enough for at least 24–48 hours)

• Non‑perishable food and snacks

• Any essential medications

• Phone charger or power bank

• Torch and spare batteries

• Battery-operated radio

• Basic first aid kit

• Important documents (or copies), such as ID and insurance details

• Personal hygiene items

• A warm layer or small blanket

• Cash and a list of key contact numbers

• Pet supplies

When the storm hits

• Stay inside and avoid unnecessary travel

• Shut windows, doors, curtains and blinds

• Keep up with updates via radio or official channels

• Unplug appliances to avoid power surge damage

• Avoid using taps and plumbing during lightning

Also, check in on your neighbours, or anyone in your community who might need a hand.

Fire and Emergency New Zealand says it’s already ramping up readiness, warning this could be a “fast-moving, high-intensity” storm with widespread impacts.

Flooding, landslides, fallen trees, and outages are all likely - especially in areas still recovering from last month’s heavy downpours.
