Landslide advice

Properties next to, above or below properties affected by existing landslides may be at increased risk of further landslides, says Head of Engineering Resilience, Ross Roberts.

“In many areas, clifftop properties with existing landslides may encounter further damage.

“If your house has a red 'entry prohibited' placard, ensure you’re following the requirement to stay out.

“If your house has a yellow 'restricted access' placard, follow the restrictions given on the placard and seriously consider avoiding any entry for the duration of the event.

“If your house is next to a property with a placard, or if you see any signs of instability, or if you are concerned about the stability of the land around your house, we recommend you are extra cautious during this likely severe weather event and you may want to consider finding alternative accommodation during heavy rain,” says Mr Roberts.  

Land instability warning signs to look for

  • new cracking in the ground around your house  
  • recent movement such as leaning power poles, trees, and retaining walls 
  • muddy water flowing down slopes or springs forming
  • loss of power or other utilities 
  • new cracks appearing inside the house eg, in gib/plaster, tiles 
  • jamming doors and windows can be a warning sign but are common in humid conditions, so if this occurs look for other warning signs 
  • unusual sounds such as trees cracking, rumbling or rocks falling or knocking together 
  • pavements sinking or finding new rocks, soil, or other debris on or around your house and property. 

Preparing for bad weather

  • Keep an eye on the weather forecast.
  • Take extreme care if you are driving in heavy rain, and delay trips if possible. Do not drive through floodwaters.
  • If life or property is at risk, phone 111.
  • Looking out for neighbours, friends and family is also important, especially if you live, work or travel in an area that is prone to flooding, slips or power outages
  • Fallen trees, blocked drains or debris on public property can be reported to Auckland Council using our online ‘Report a Problem’ tool.
  • If your property is damaged, take photographs for your insurer as early as possible

If out and about in a storm

  • Always drive to the weather conditions and never drive through floodwaters.
  • If you get stuck in a flood, get out of your car and move to higher ground immediately, taking great care in the floodwaters.
  • Never play in or walk through floodwaters unnecessarily, you may encounter unseen objects, dangerous debris or holes.
  • If driving at night, drive slowly, especially through flood-prone areas as you may encounter flooding at short notice.
  • Never attempt to drive over slips and treat power lines as live at all times.
  • Check on neighbours and family, especially if they are in at-risk areas or might be affected by flooding or slips.

Pets and livestock

If you live on a rural property, think about your livestock rotation, especially if areas of your farms are flood-prone.

  • If you have to evacuate, take your pets with you – if you can do so safely – or take them to a safe shelter place.
  • If you have to leave your animals behind, make sure they’re in a secure and sheltered place either inside or outside your home.
  • If you have livestock or horses in paddocks near waterways that have the potential to flood (streams, rivers etc.), move them to higher ground. Make sure your stock have access to clean feed and water in their new contained space until they can be returned to their paddocks.
  • If you need more detailed guidance, check the animals affected by emergencies factsheets on the Ministry for Primary Industries website.

Tornado tips

There is also a possibility of tornado conditions but, as always, it is hard to pick where the greatest risk is and almost impossible to predict where a tornado might appear, so remember:

  • If you see a tornado, seek shelter immediately.
  • If you’re inside, stay away from doors and windows, and stay downstairs if you’re in a multi-storey building.
  • For added protection, get under something sturdy, cover your body with a blanket or mattress and protect your head with your hands.
  • If you’re outside, lay flat in a gully, ditch or low spot on the ground and protect your head with an object or your arms.
  • If you’re in a car, pull over and shelter in a low spot (not under or near the car).
