People around the country are being warned to prepare for widespread heavy rain over the next few days - and there's an increased risk of flooding and landslides.
National Emergency Management Agency director John Price said the organisation was working with Civil Defence to ensure they had the resources they needed before bad weather arrived.
Heavy rain warning and a severe thunderstorm watch for Auckland
MetService has issued an orange heavy rain warning and a severe thunderstorm watch for Auckland, including Great Barrier Island from midday to midnight on Tuesday.
The region could see localised torrential rain of around 50mm to 70mm, and an active front could bring thunderstorms on Tuesday afternoon and evening.
Auckland Emergency Management Duty Controller Parul Sood said Aucklanders should remain vigilant and have an emergency plan in place if they needed to evacuate, especially those people who live in isolated areas, or areas prone to flooding.
People should check the Auckland Emergency Management website and social media channels to see whether civil defence centres had been activated, she said.
AEM head of engineering resilience Ross Roberts said properties next to, above or below properties affected by existing landslides may be at increased risk of further landslides.
