MBIE Wood Energy Strategy + Action Plan (October 2025)

The NZ supply/policy documentation for the V1+ biomass-heat roadmap (RT_157)

MBIE (with Te Uru Rākau – NZ Forest Service) Wood Energy Strategy (ISBN 978-1-991409-72-0) + Action Plan (978-1-991409-73-7), Oct 2025. Government strategy to accelerate wood energy, chiefly for industrial process-heat decarbonisation. Establishes NZ’s wood-fuel supply picture, the use-case logic, and the regulatory pathway — including the air-quality (NES-AQ) consenting reform that maps to the model’s airshed_restricted feasibility filter. The supply-side companion to the biomass-as-heat picture (OT_073, int_001).

Summary

The Strategy sets a vision and six objectives to grow wood energy as a reliable, affordable, sustainable fuel — primarily replacing coal/gas in industrial process heat — using forestry residues and low-grade logs (not higher-value timber). It quantifies NZ’s wood-fuel supply, frames where wood energy fits (high-temperature, storable, grid-constrained, good-logistics sites), and via the Action Plan sets out government actions on supply, investment, end-user barriers, exports, market transparency, and sustainability. Wood energy is explicitly a lower-value use in the forestry “value triangle,” so the strategy directs it at residues and surplus low-grade material.

Key claims

- claim: "Vision & headline target: NZ accelerates wood energy as a reliable, affordable, sustainable energy resource (domestic + export), creating regional forestry/wood jobs. Production forestry is NZ's largest renewable biomass resource. ~40% of fossil-fuelled process heat could be replaced by wood energy by 2050. Six objectives: (1) improve wood-fibre supply availability; (2) enable private investment in production capacity; (3) reduce barriers for end users; (4) promote export-market access + foreign investment; (5) improve market transparency & coordination; (6) promote sustainably sourced wood energy."
  source_location: "Strategy — snapshot (p4); How the Government will support wood energy (p15–16)"
- claim: "Forestry resource & supply: ~2 million ha commercial plantations; ~40 million tonnes of wood harvested/yr; forestry + wood processing ~$8.5 billion revenue/yr. EECA estimates 7–8 million tonnes of residues or low-grade logs could be available each year for wood energy without impacting existing wood-fibre users (excludes K-grade 4–5 Mt and future short-rotation forests). Feedstocks: wood-processing co-products (sawdust, chip), in-forest/harvest residues, low-grade (KI/KIS) logs, and short-rotation forestry — Scion estimates short-rotation forestry could replace ~6% of NZ's annual fossil-fuel demand using <1% of land area."
  source_location: "Strategy — NZ's forestry resource (p6); The potential for wood energy (p8)"
- claim: "Use-case logic + the 'value triangle': wood energy is a LOWER-value use of wood fibre (bioenergy 0.6–1 / biofuels 0.4–1 jobs per 1000 oven-dried tonnes, vs biomaterials 3–10 / engineered wood 4–9) — so it should use residues and surplus low-grade logs, not higher-value timber. Wood energy is particularly useful where higher temperatures are needed (process steam, kiln drying, particle board), storable energy is needed (electricity generation, dry-year security), there are grid/electrification capacity constraints, or logistics favour it. ~1 million tonnes of green wood fibre is used for process heat now; replacing ~40% of process heat would need ~4 million tonnes more."
  source_location: "Strategy — Value Triangle (Fig 1, p6); Energy security (p9–10)"
- claim: "Anchor case + market: Genesis Energy targets 300,000 t/yr of torrefied (black) pellets to Huntly Power Station by end-FY2028 to displace coal (Huntly coal generation produced 1.35 Mt CO₂-e Jul 2023–Jun 2024); government estimates reductions of 1.1 Mt CO₂-e (EB2) + 1.6 Mt CO₂-e (EB3). NZ has four white wood-pellet facilities; Fonterra imports white pellets (Clandeboye); Nature's Flame exports white pellets (export markets Japan, Korea, EU). A medium-sized sawmill employs ~130 people; recent closures in Tasman, South Waikato and Ruapehu show regional vulnerability. Ngāi Tahu Farming + Crown Forestry are trialling short-rotation forestry (5,400 ha Hikawaikura Forest, Hurunui)."
  source_location: "Strategy — Huntly case study (p10); regional contribution (p11)"
- claim: "Regulatory & sustainability (Action Plan): the key end-user barrier is AIR-QUALITY consenting for wood-energy combustion — replacement provisions to the National Environmental Standard for Air Quality (NES-AQ) are required to be in place by mid-2027 (subject to Ministerial decisions); RMA reform requires consenting authorities to decide a specified energy/wood-processing consent within one year. MPI is planting a 5,000 ha biomass-forestry programme (2021–2030); EECA ran an aggregation-facility RFP (Oct 2025). Sustainability: wood energy is NOT automatically 'carbon neutral' (net emissions depend on sourcing/what it replaces; combustion sits outside the NZ ETS); NZ is well-positioned (fast-growing plantation, not old-growth), but even harvest residues reduce forest carbon storage somewhat."
  source_location: "Action Plan — Objective 1 (p3), regulatory environment / NES-AQ (p5); Strategy — emissions & sustainability (p12)"

Neobiome Intelligence relevance

The supply/policy backbone for activating the V1+ biomass-heat option. It confirms the model’s framing — biomass = process heat (high-temperature, storable, grid-constrained), not electricity — and supplies three things the biomass roadmap needs:

1. Feedstock is not a binding constraint regionally. EECA’s 7–8 Mt/yr of available residues dwarfs a community district-heat plant’s needs (Interview I [INT_001]‘s 1–5 MW, ~50 km radius) — so the model’s biomass feasibility is about local airshed + logistics, not national supply.
2. The airshed_restricted feasibility filter is real and dated. The Action Plan names air-quality consenting (replacement NES-AQ by mid-2027) as the end-user barrier — concrete documentation for the biomass feasibility_rule the spec flags (§9 heat-options batch).
3. A fuel-cost design constraint (value triangle): the model’s biomass fuel should be residues/low-grade (cheap, surplus), carrying an opportunity-cost vs export — not whole logs.

⚠ It does not fill the biomass cost cells — wood-fuel price (NZD/tonne → NZD/kWh-fuel), community boiler installed cost (NZD/kW_th), boiler efficiency/calorific value, woodlot yield — which remain the gaps to activate biomass (RT_247–249, below). Thesis: bioenergy/forestry policy, regional development (Tasman named), Māori-landowner opportunity (Ngāi Tahu short-rotation), the sustainability/carbon-neutrality debate, energy security (gas decline, dry-year coal). Resolves the wood-energy half of RT_157 (the geothermal strategy’s full PDF was not obtained; low priority, utility-scale, out of community scope).

Research targets

Research gaps

• RT_247 (new): NZ wood-fuel price (chip / white & torrefied pellet / residue, NZD/tonne → NZD/kWh-fuel) + boiler efficiency + wood calorific value — the biomass fuel-flow cells.
• RT_248 (new): NZ community-scale biomass boiler / district-heat installed cost (NZD/kW_th) + wood-stove cost — the biomass technology cost cells.
• RT_249 (new): NZ airshed / NES-AQ wood-burning restrictions by region (the biomass airshed_restricted feasibility filter; replacement NES-AQ due mid-2027).
• Geothermal (noted): the MBIE “From the Ground Up” geothermal strategy full PDF (RT_157’s other half) — headlines captured; low priority (utility-scale, out of NI community scope).
