New Zealand’s Ministry of Education has signalled a 3-region targeting strategy for the Off-Site Manufacture (OSM) Panel cycle covering Taranaki, Hawke’s Bay, and Otago. For NZ-LBP head contractors, modular suppliers, and Australian-based exporters supplying through Cook-Strait logistics, the procurement window across these three regions is materially different from the Auckland / Christchurch / Wellington main-centre programmes.
This guide breaks down the regional demand signals, NZBC producer-statement chain requirements, and the seismic / climate detailing that varies by region.
Why Taranaki + Hawke’s Bay + Otago
The Ministry of Education’s OSM Panel cycle prioritises regions where:
- Roll growth is forecast above 1.5% annually through 2030
- Existing school stock includes high proportion of 1960s-1980s relocatable buildings due for replacement
- Regional council / MoE infrastructure spend is co-funded through Provincial Growth Fund successor programmes
- Local LBP head-contractor capacity exists but supplementary modular supply is needed for programme acceleration
Taranaki, Hawke’s Bay, and Otago all sit inside this profile. They are not the biggest by absolute roll count — but they are the three regions where OSM Panel supplementary supply has the highest commercial leverage for tier-2 modular suppliers.
Region-by-Region Compliance Stack
Taranaki — Wind + Volcanic Ash + Coastal Salt
Compliance considerations:
- NZS 1170.5 seismic: Z=0.18-0.25 across the region (lower than Wellington 0.40 but higher than Auckland 0.13)
- NZS 1170.2 wind: Mid-band V_R based on coastal proximity; New Plymouth coastal sites approach Region 3
- Volcanic ash loading: Mount Taranaki ash-loading scenarios under NZBC E1 Surface Water + AS/NZS 1170 design for unusual loads; standard residential roof structures often non-compliant
- Coastal salt corrosion: NZS 3404 Atmospheric Category C5-I for coastal sites within 1km of coastline; galvanizing or marine-grade coating required
Hawke’s Bay — Seismic Premium + Cyclone Gabrielle Recovery Context
Compliance considerations:
- NZS 1170.5 seismic: Z=0.36-0.40 across the region; among the highest in NZ outside Wellington
- Cyclone-equivalent wind loading: Post-Cyclone Gabrielle, expectations have shifted on resilience; NZBC E1 + E2 weatherproofing detailing scrutinised more rigorously
- Flood-risk site assessment: Council-level flood overlays now required on schools rebuild programmes; floor levels and ground-clearance critical
- TC2 / TC3 land classification: Liquefaction risk on Heretaunga Plains; deep foundation alternatives often required vs simple pad footings
Otago — Snow Loading + Alpine Cold
Compliance considerations:
- NZS 1170.5 seismic: Z=0.18-0.30 across Central Otago and Coastal Otago; varied by site
- NZS 1170.3 snow: Alpine sites (Wanaka, Queenstown, Central Otago) require snow loading 1.0-2.0 kPa governing roof structural capacity
- Thermal performance H1: NZBC H1 amendments (2022/2023) significantly increased insulation requirements for South Island climate zones; modular suppliers using pre-2022 H1 detailing now non-compliant
- Ground-frost detailing: Pile foundation, sub-floor insulation, and services-trench depth all need adjustment for Central Otago alpine conditions
NZBC Producer Statement Chain
Across all three regions, the NZ Building Consent Authority (BCA) acceptance pathway requires:
- PS1 (Producer Statement: Design) — registered structural engineer, NZS 3404 / NZS 1170 design verification
- PS3 (Producer Statement: Construction Review – Off-Site) — verifies module manufactured in factory environment to design
- PS4 (Producer Statement: Construction Review – On-Site) — verifies installation, inter-module connections, services interface
For Australian-based modular suppliers exporting to NZ, the PS3 chain is the critical evidence. BCA reviewers require named NZ-registered engineer sign-off, not generic factory inspection certificates.
Cost Benchmarks for OSM Panel Supplementary Supply
Current NZ$ benchmarks for OSM Panel modular classroom delivery across the three regions:
- Taranaki coastal sites (Class 9b, NZS 1170 mid-band): NZ$2,400-$3,800/m² supply DAP Port Taranaki
- Hawke’s Bay (Class 9b, NZS 1170 seismic premium): NZ$2,500-$4,000/m² supply DAP Port Napier (seismic detailing +10-15% premium)
- Otago alpine (Class 9b, NZS 1170.3 snow): NZ$2,600-$4,200/m² supply DAP Port Otago or Port Chalmers (snow + H1 thermal premium)
Programme: 6-9 months from design lock to BCA Code Compliance Certificate.
Port-of-Discharge Logistics by Region
Taranaki
Port Taranaki (New Plymouth) — direct discharge, oversize permit through NZTA / Taranaki Regional Council. Inland haul to Hawera, Stratford, Inglewood feasible. Alternative: Auckland discharge with Cook Strait Ferry routing for North Island inland projects.
Hawke’s Bay
Port Napier — direct discharge but limited berth size; oversize modules >4.5m width need pre-coordination 4-6 weeks ahead. Alternative: Tauranga discharge + State Highway 2 inland haul (4-5 hour transit).
Otago
Port Otago (Port Chalmers) or Port of Bluff — direct discharge for South Island delivery. Alpine sites (Wanaka, Queenstown) need Class 1 oversize permits through NZTA for inland haul; winter route restrictions on State Highway 8 Lindis Pass and SH8B.
OSM Panel Application Differentiators
For modular suppliers seeking OSM Panel membership across these three regions, applications that score highest demonstrate:
- Region-specific NZS detailing — not generic NZ design, but explicit reference to the region’s seismic Z, wind V_R, snow loading, and H1 thermal class
- NZ-registered engineer PS3 chain — named individuals, signed certifications, not generic factory QA documents
- BCA-specific compliance track record — references to consent applications across the three regions’ Building Consent Authorities
- Logistics maturity — port-of-discharge strategy, NZTA oversize permit experience, regional council liaison
- Cyclone Gabrielle / climate-resilience reference — particularly for Hawke’s Bay applications, demonstrated awareness of post-Gabrielle expectations

FAQ
Which NZ regions does the Ministry of Education OSM Panel prioritise in 2026?
Across the current cycle, Taranaki, Hawke’s Bay, and Otago are the three priority regions for supplementary OSM Panel supply, based on roll growth forecasts, ageing relocatable stock replacement, and regional infrastructure co-funding profile.
What’s different about modular delivery in Hawke’s Bay post-Cyclone Gabrielle?
Higher scrutiny on NZBC E1 + E2 weatherproofing detailing, flood-risk site assessment with council overlays, and TC2 / TC3 liquefaction risk on Heretaunga Plains driving deep foundation alternatives. Plus existing NZS 1170.5 Z=0.36-0.40 seismic premium.
What NZBC compliance applies to OSM Panel modular classrooms?
NZBC Class 9b learning environments. The producer-statement chain requires PS1 (design) + PS3 (off-site manufacture) + PS4 (on-site installation), all signed by NZ-registered engineers.
What does OSM Panel modular cost in 2026 across these three regions?
Taranaki: NZ$2,400-$3,800/m² supply. Hawke’s Bay: NZ$2,500-$4,000/m². Otago: NZ$2,600-$4,200/m² (snow + H1 premium). Delivery programme: 6-9 months.
Can Australian-based modular suppliers bid OSM Panel supplementary supply?
Yes, provided the supplier partners with an NZ-LBP head contractor for on-site installation and provides PS3 chain signed by an NZ-registered structural engineer. The BCA does not accept Australian-engineer sign-off as a substitute.
