Frequently Asked Questions Emergency Management Survey (October 2025) 

How long does the survey run?

The survey will run from 17 October until 4.30pm on Friday 7 November 2025.

How can I fill out the survey?

The survey can be filled out online on this page: letstalk.bullerdc.govt.nz/emergency-management-survey

Paper surveys and information can be found at the Buller District Council Westport service centre or the Sue Thomson Casey Memorial Library in Westport. 

Is the survey anonymous?

We ask that you supply your name and email address or phone number to help ensure the source and accuracy of the survey responses we receive. Any sharing or publication of survey results, including with local Civil Defence Emergency Management, will be in an anonymised format.

How will the survey results be of use?

We are preparing an enhanced flood evacuation response plan for Westport, Carters Beach and Snodgrass Road.

The planning we’ve done to date is based on good information about our community’s capabilities and preparedness such as Census data and statistical information about the population, households and local tourism. But we need the help of our local residents to confirm the reliability of this information and improve our knowledge on the extent the community is able to self-evacuate if a major flood warning confirms an evacuation is necessary because of serious safety risks.

The plan will be a living document so new information will be considered and incorporated into it as we go along.

When will the enhanced evacuation plan be made public?

We will share more information about the plan with the community later in the year. It is important to us that people in the community know who is doing what in an emergency and what they can do to be better prepared.

Who can participate in the survey?

The survey is intended for residents of Westport, Carters Beach and Snodgrass Road who are aged 18 and over. We only need one response for each household.

How will people know when to evacuate?

There would be wide-spread messaging if an emergency flood evacuation were required. Sources of information will include radio, television, social media, websites, mobile public announcement systems and, at the most appropriate time, an emergency mobile alert. Door knocking may occur if other communication methods are not available.

What are the flood evacuation triggers?

Deciding on an evacuation is a complex matter involving the consideration of many things including severe weather warnings (red or orange heavy rainfall warnings from MetService), cumulative rainfall, field measurements and observations (including from river and rain gauges), and geotechnical and structural performance monitoring, satellite imagery, rain radar (if available), and expert opinions.

A key factor for Westport is ensuring people can get across the bridges from the main township to places of safety in advance of a major flood. In all cases, avoiding or reducing serious risk to human life is a primary concern.

Other important contextual considerations for an evacuation decision may include: adverse weather conditions reducing effectiveness of emergency resources, road or bridge closures, relatively large numbers of people at risk (eg, peak tourist season or visitors attending an event), and time of day – the evacuation process will be much safer if it can start and be completed during daylight hours.

Would there be advance notice of an evacuation to give people time to prepare in a flooding emergency? 

Severe weather warnings, cumulative rainfall data and river and rain gauges – among other tools –provide good information to help predict a major flooding event. We anticipate 12 or more hours’ notice, but this will depend on the circumstances at the time.

Is the survey only for flood-related evacuations?

The Plan we are working on is focussed on flooding, but the learnings from this process will apply to most if not all other emergency situations. Improved planning and preparedness help in all emergency circumstances.

How can I find out more?

Copies of these FAQs and paper survey forms will be placed at the Buller District Council Westport service centre or the Sue Thomson Casey Memorial Library in Westport.
