Summary

The structured companion dataset to OT_024 Global EV Outlook 2026. Long-format Excel with 20,631 rows covering EV stock, sales, sales share, stock share, charging infrastructure, oil displacement, electricity demand, and battery deployment across countries and modes. Categories: Historical (19,550 rows, 2010-2025) + Projection-CPS (Current Policies, 531 rows) + Projection-STEPS (Stated Policies, 550 rows). NZ-specific scope: 323 rows of historical data only — no projection scenarios for NZ. Time series 2010-2025 reveals the full NZ EV trajectory including the 2023 27% sales-share peak, 2024 Clean Car Discount removal crash (11%), and 2025 recovery (12%) — context that OT_024’s Figure 1.2 chart-read 12% number obscures.

Key claims

  • Dataset structure — 20,631 rows × 9 columns (region_country, category, parameter, mode, powertrain, year, unit, value, Aggregate group); long-format. Categories: Historical (19,550 rows), Projection-CPS (Current Policies, 531 rows), Projection-STEPS (Stated Policies, 550 rows). Parameters: EV stock, EV sales, EV sales share, EV stock share, EV charging points, oil displacement (Mbd + Mlge), average capacity per EVSE / per EV, electric LDVs per charging point, electricity demand, battery deployment. Modes: Cars, Buses, Trucks, Vans, 2-and-3-wheelers, EVSE, EV. Powertrains: BEV, PHEV, FCEV, ICEV, slow/fast/ultra-fast charging. RD_006
  • NZ EV sales (Cars) historical 2010-2025: BEV 10 → 6,800 vehicles/year (peaked 21,000 in 2023); PHEV 2 → 4,800 (peaked 9,200 in 2022); FCEV 19 in 2024. 2025 combined sales ~11,600 cars. The 2023 peak → 2024 collapse (BEV 21,000 → 6,300, PHEV 9,000 → 3,400) is the Clean Car Discount removal (Jan 2024) signature; partial 2025 recovery driven by rising fuel prices and Chinese-import affordability. RD_006
  • NZ EV sales share (Cars) historical 2010-2025: 0.015% → 12%. Trajectory: 2010 (0.015%) → 2015 (0.6%) → 2017 (3.4%) → 2020 (6.6%) → 2021 (9.4%) → 2022 (24%) → 2023 (27%, peak) → 2024 (11%, Clean Car Discount removal cliff) → 2025 (12% recovery). The OT_024 Figure 1.2 12% figure obscures both the 27% peak and the policy-driven crash — full context lives in the dataset. RD_006
  • NZ EV stock (Cars) 2025 ≈ 128,000 vehicles: 87,000 BEV + 41,000 PHEV + 38 FCEV. Trajectory: BEV 14 (2010) → 87,000 (2025); PHEV 2 (2011) → 41,000 (2025); FCEV trivial. Stock share 4% of total NZ car stock (vs 12% sales share — large diesel/petrol legacy fleet). Implies long lag before stock-share converges with sales-share at current trajectory. RD_006
  • NZ EV stock by other modes 2025: Buses 750 BEV + 1 PHEV (14% stock share — most electrified mode in NZ); 2-and-3-wheelers 3,000 BEV (1% share); Vans 1,900 BEV + 92 PHEV + 6 FCEV (0.26% share). Buses are the most electrified mode by stock share — earlier policy attention and fleet replacement cycles. RD_006
  • NZ EV charging infrastructure 2017-2025: Publicly available fast chargers 100 → 910 (9× growth); slow 89 → 290 (3× growth); ultra-fast 54 (first 2020) → 270. Total public charging stock 2025 ≈ 1,470 chargers. Electric LDVs per charging point 57 (2017) → 88 (2025) — vehicle stock growing faster than charging buildout (densification). Average capacity per EVSE 50 → 61 kW/EVSE (gradual upgrade). RD_006
  • NZ EV-related average capacity per EV 0.88 (2017) → 0.69 kW/EV (2025) — declining ratio. Interpretation: home/private charging capacity not scaling per-EV with stock growth; reliance on public infrastructure rising or charging-time-shifted to off-peak. RD_006
  • NZ has NO PROJECTIONS in this IEA dataset. Projection-CPS and Projection-STEPS scenarios only exist for major markets (China, EU, US, India) and macro aggregates (no “Oceania” aggregate). The OT_024 Chapter 9 510M global fleet by 2035 and 50% sales share figures do NOT have an explicit NZ breakdown. Any NZ EV demand forecast for NI must be modelled separately (RT_117 MBIE EDGS area). RD_006
  • XLSX format note — dataset is long-format suitable for pivot analysis. Each row is one (country × category × parameter × mode × powertrain × year) observation. Total row counts: Historical 19,550 (2010-2025 for established parameters; up to 2017 onwards for charging infrastructure), Projection-CPS 531 rows, Projection-STEPS 550 rows. Empirical data is annual. RD_006
  • Powertrain definitions (Definitions sheet): EV = electric vehicle (umbrella); BEV = Battery Electric Vehicle (pure battery); PHEV = Plug-in Hybrid Electric Vehicle (battery + ICE); FCEV = Fuel Cell Electric Vehicle (hydrogen); ICEV = Internal Combustion Engine Vehicle (baseline comparator). For NZ analysis: BEV is the dominant trend, PHEV second, FCEV trivially small. RD_006
  • Charging power categorisation (slow / fast / ultra-fast): IEA distinguishes Publicly available slow (≤22 kW typical AC), Publicly available fast (typically 22-150 kW DC), Publicly available ultra-fast (>150 kW DC). NZ 2025 split: 910 fast + 290 slow + 270 ultra-fast. The fast band dominates — NZ public charging is mostly mid-tier DC suitable for highway corridor coverage rather than urban kerbside (slow) or motorway megawatt (ultra-fast). RD_006
  • Empirical validation of OT_024 Figure 1.2 NZ point — dataset confirms NZ 2020 sales share 6.6% (close to chart-read 7% in OT_024 key_claim) and 2025 sales share 12% (exact match). NZ 2020 figure is in fact 6.6% — slightly lower than the chart-read 7% in OT_024 key_claim. RD_006

Neobiome Intelligence relevance

  1. First wiki source with full NZ EV time series 2010-2025 — sales, stock, sales share, stock share for Cars/Buses/Vans/2-3-wheelers. NI calculation skill for NZ EV scenarios can pull empirical baselines here rather than estimating.
  2. NZ EV stock 2025 ≈ 128,000 cars is the basis for any V2H/V2G community-pilot scaling math. At 128,000 EVs × 60 kWh avg battery × OT_024 ~±8 kWh/day V2G flex = NZ EV fleet has ~1 GWh/day theoretical V2G flex potential at full V2G penetration. Currently constrained by V2G-capable model availability (~1.5% per OT_024) and absent NZ V2G regulatory framework (RT_121).
  3. Clean Car Discount cliff (2024) — first empirical NZ policy-sensitivity finding in wiki. Sales share dropped 60% (27% → 11%) following the Jan 2024 discount removal. Material for the analysis on NZ EV/energy policy resilience. Confirms IEA’s Chapter 1 narrative about “policy responses … shape the global car market for years to come” applies sharply in NZ.
  4. NZ public charging trajectory — fast 910, slow 290, ultra-fast 270 (= 1,470 total public chargers 2025). LDVs per charging point ratio rose from 57 to 88 between 2017 and 2025 — vehicle stock growing faster than charging buildout. Stress signal for NZ corridor charging coverage; relevant for the analysis on regional/rural EV access (Tasman included).
  5. Forecasting gap for NZ — IEA dataset has no NZ projections; only major markets + macro aggregates. RT_117 (MBIE EDGS successor) is the high-priority gap to fill for NZ-specific NI EV forecasts.
  6. Empirical validation of OT_024 Figure 1.2 — 2020 NZ sales share 6.6% (close to chart-read 7% in OT_024 key_claim); 2025 exact 12%. Sharpens the OT_024 imprecise chart reading.

What this dataset does NOT contain:

  • NZ projection scenarios (only major markets + macro aggregates)
  • District- or region-level NZ data (RT_119 NZTA still needed for sub-national)
  • V2G-specific data (model availability, regulatory progress — all in OT_024 narrative)
  • Vehicle price data (the Abstract mentioned “vehicle price data in selected markets” — price_p0_2025USD parameter exists with 53 rows but limited country coverage; not extracted here)

Research targets

Documents to retrieve

(No new RTs added — companion to OT_024 which already added RT_119, RT_120, RT_121. The vehicle-price slice could be a future RT if it becomes load-bearing.)

Research gaps

  • (Updates RT_119 status) — IEA dataset gives NZ country-aggregate time series; NZTA primary still useful for district/region breakdown and most recent rolling data. RT_119 stays Open as “partially addressed”.
  • (Reinforces RT_117) — IEA dataset confirms no NZ projection scenarios. MBIE EDGS successor (RT_117) is the canonical NZ-specific forward modelling source.
