operating value

— of operating value a year, against — invested in REx — before the strategic pillars below.

Operating return counts the annual-cash pillars only — efficiency, insurance & compliance. Avoided losses accrue over the LTP horizon; reputation is deliberately unpriced.

Indicative figures — a data assessment turns them into your actual return.

Pillar 01 · Efficiency · no modelling required

You already do this work — and pay for it four times

Four teams, four budgets, four consultants producing the AMP, the LIMs, the s104 reports, the Group Plan, the CCRA — each from its own fragmented evidence. Your total spend from Step 1, split across the four teams.

Pillar 04 · Compliance

Meet the obligations — with one defensible method

A wave of new duties lands on councils, each demanding evidenced, consistent risk. REx serves them all from one auditable base — and when four teams disagree on the same property, the legal exposure lands on you.

physical-risk evidence for climate-related disclosures, versioned & defensible

The compliance work is not optional and not new — REx changes only that it's done once, consistently, and defensibly. Legal-exposure figure is indicative.

Pillar 02 · Avoided losses

Avoided losses & smarter capital, over time

Expected annual loss rises either way — climate change, multi-hazard and growth mean more to lose every year. REx doesn't stop that; it lets you target the capital that most reduces risk, so your loss climbs more slowly. The widening gap between the lines is loss you avoid.

Expected annual loss today ≈ —, about 0.5% of your — asset base. Change your asset base in Step 1 above.

Illustrative trajectory — expected annual loss escalates ~3.5%/yr under business-as-usual and ~2%/yr with REx (both rise; growth and multi-hazard mean more to lose every year). The REx path assumes prioritised interventions are actually funded. Replace with your quantified exposure and programme.

Pillar 03 · Insurance & capital

Insurance affordability, insurability & cost of capital

Insurers price what they can't see as worst-case — and coastal councils are already facing rising premiums and non-renewal. Demonstrable, quantified risk management is what keeps cover affordable and available, and it shapes how markets price your debt.

Estimated current premium ≈ —, scaled to your asset base, with an indicative ~10% improvement from evidenced risk management. Change your asset base in Step 1.

Negotiate, don't accept

Bring the insurer evidenced exposure and a funded reduction programme, not a spreadsheet of assets. Councils that can show their working get better terms.

Inform self-insurance & retention

Know which exposures to carry, transfer, or reduce — and size reserves on evidence rather than fear.

Premium improvement is illustrative and depends on your insurer and programme. Insurability and cost-of-capital effects are real but council-specific — quantified in the value assessment.

Pillar 05 · Reputation

Community trust & decisions that hold

The hardest decisions a council makes — managed retreat, where growth goes, whose property is affected — are won or lost on trust. One transparent, plain-language evidence base is what lets communities, iwi and elected members engage with the same picture.

Elected-member confidence

Councillors defend decisions they can see the evidence behind — consistent answers across the table, not four consultants contradicting each other.

Community & iwi engagement

Interactive maps and plain-language risk narratives bring people into the conversation, building buy-in for hard adaptation choices rather than resistance.

Fewer contested decisions

A consistent, defensible method reduces submissions, appeals and the reputational cost of decisions that look arbitrary.

Post-event standing

When an inquiry asks "what did you know and when," a versioned evidence base is the difference between vindication and liability.
