TRANZFOR study

• Funded by the EU and Forestry Commission

• Met with key Scion and other NZ fire

professionals

• Undertook a review of how NZ is managing

wildfire risk, notably in the face of climate

change

• Explored how Scion systems might suit UK

needs

• Shared UK experiences as appropriate

NZ Rural Fire Jurisdiction

Forest and Rural Fires Act 1947 – first legislation dedicated wholly to rural fire

Forest and Rural Fires Act 1955 – all aspects of rural fire legislation delivered by the NZ Forest Service

Fire Service Act 1975 – Urban Fire Districts administered by Fire Service – (3% of NZ - respond operationally outside UFD)

Forest and Rural Fires Act 1977 – Rural Fire Authorities set up (97% of NZ)

Forest and Rural Fire Act 1977

Relates to the safeguarding of life and

property by the prevention, detection,

control, restriction, suppression and

extinction of fire in forest and rural areas

and other areas of vegetation in New

Zealand

Forest & Rural Fire Management

Page 12: Wildfire risk management in New Zealand - possible lessons ...€¦ · Wildfire risk management in New Zealand - possible lessons for current and future ... spatial analysis model

Role of National Rural Fire Authority

(NRFA)

Providing support and co-ordination • develop & audit minimum national standards

• performance assessment of Rural Fire Authorities

• monitoring/reporting fire danger nationwide

• administer a National Rural Fire Fighting Fund

• providing technical advice

• providing grants for equipment, PPE, weather ob’s

• promote and encourage rural fire research

• coordinating national & international deployments

Page 13: Wildfire risk management in New Zealand - possible lessons ...€¦ · Wildfire risk management in New Zealand - possible lessons for current and future ... spatial analysis model

Role of Rural Fire Authorities (RFAs)

• Prevention, detection and suppression of vegetation fires

• Responsible for fire reduction & readiness activities including:

Monitoring daily fire danger

Declaring fire seasons

Issuing fire permits

• Principal Rural Fire Officer for a RFA has statutory powers under the Forest and Rural Fires Act 1977

Role of Rural Fire Authorities (RFAs) –

con’t

Section 12 – Forest and Rural Fires Act 1977

Rural Fire Authorities must promote and carry out

effective fire control measures in their districts

Rural Fire Authorities must comply with the

standards set by the NRFA

Rural Fire Authorities must keep and maintain a

current fire plan for their districts

Reduction – fire mitigation and prevention, wildfire threat

analysis, risk assessment and planning, and fuels

management

Readiness – setting fire suppression preparedness levels,

adequate resourcing of Rural Fire Authorities, and managing

fire season status and activities

Response – responding to fires with adequate resources,

safe and effective fire suppression, accurate predictions of

fire behaviour, and decisions around evacuation or asset

protection

Recovery – understanding and learning from fire events to

reduce the impacts, prevent reoccurrence and increase

community resilience

WTA is now the required basis for

compliance with the NRFA Minimum

Standard on the Assessment of Fire

hazard, which became operative in July

2013.

WTA is defined as "a systematic method

of identifying the level of threat a

particular area faces from wildfire. The

level of threat is generally related to a

combination of ignition potential, potential

fire behaviour and the values threatened.“

WTA in New Zealand is a GIS-based

spatial analysis model and strategic

planning tool which enables fire

managers to objectively identify the areas

of greatest threat from wildfire at a

strategic level.

NZ Wildfire Threat Analysis System

Page 27: Wildfire risk management in New Zealand - possible lessons ...€¦ · Wildfire risk management in New Zealand - possible lessons for current and future ... spatial analysis model

NZ Wildfire Threat Analysis (WTA)

RISK = ignition potential; HAZARD = potential fire behaviour;

VALUES = values threatened

Risk management in NZ

“Better decisions [about wildfire] will be made if they are developed through the consistent application of contemporary risk management concepts…”

(Murray Dudfield, NZ NRFA)

Page 29: Wildfire risk management in New Zealand - possible lessons ...€¦ · Wildfire risk management in New Zealand - possible lessons for current and future ... spatial analysis model

“managing fire-related risk to land is fundamentally an issue of land management and not fire management”

Compare and contrast

(Murray Dudfield, NZ NRFA)

High–level conclusions

• The UK could benefit from learning about wildfire risk

management in countries like New Zealand – such

experience and expertise is freely shared

• NZ wildfire risk and fire management systems, especially

FWI, FBP and WTA, could form the basis of extending

UK systems

• Wildfire systems are unlikely to succeed without

appropriate policy/regulatory/legal infrastructure; NZ

experience is to work across all rural land-uses

• Consider approaches like Wildfire Threat Analysis in

context of International Disaster Risk Assessment

principles and systems (e.g. ISO 31000:2009)
