Demo data. Both companies, their stands, plots, sales, costs and locations are synthetic. Locations are approximate region centres with jitter, not surveyed coordinates. The only real input is the MPI Export Pruned log price series. ML results are labelled experimental and compared against a baseline.
Real MPI Export Pruned series with a gradient-boosting forecast. The naive baseline is shown dashed. Click a point for its value.
Tree growth: measured plots and model Experimental
Each dot is a plot measurement. The line is the model's prediction for the selected species. Click a dot to open its stand.
Cost per m³ and anomaly review Experimental
Flagged quarters are for review, not confirmed faults. Click a quarter for detail.
Scenario: price, yield and cost Demo
Move the sliders. Contribution recalculates from the last four quarters.
Advisor: what to do next Rule-based
Recommendations are calculated from the data in the current filters. No language model is used. Click a recommendation to see the stands or quarters behind it.
Thresholds: rotation age from each stand; region concentration above 40% of area; price sensitivity 10%Outlook: 5 and 10 years from the stand growth forecast (experimental); 20 years extrapolated at half the 5–10 year rate
Units & glossary Reference
How to read the numbers on this page.
ha — hectares of planted or harvested area
m³ — cubic metres of logs (volume)
c/L — cents per litre, adjusted retail fuel price
Rotation age — age at which a stand is due for harvest
Ready — age ≥ 25 and predicted height ≥ 28 m (a rule, checked by a person)
Colours — green harvested, amber ready for harvest, blue growing
Experimental — model output, always shown next to a simple baseline
Demo — synthetic data for layout and testing, not real forests
Harvest-ready and stand table Demo
Ready = age ≥ 25 and predicted height ≥ 28 m (a rule, reviewed by a human). Click a column header to sort. Click a row to open the stand.
Ask the forest data DemoDeterministic
Counts come from the data, not from a language model. Examples: how many trees harvested in Canterbury, trees harvested within 50 km of -45.6, 169.9, stands ready for harvest in Northland, what is the price forecast.
Answered locally from the demo data. No AI service or API key is used, so there is no limit.
Revenue calculations DemoPublished
Moved here from the Forestry workspace. Export revenue is published MPI 2025 data. The harvest revenue, cost and sensitivity figures use demo volumes and assumed costs.
Haulage tracking DemoMBIE diesel
Simulated truck on the Kaingaroa to Port of Tauranga route. It runs loaded out and empty back. Clock runs 30× real time. Not live GPS.

Rotorua → Tauranga log transport Simulated inputsDemo data
Compares direct road haulage with road-plus-rail. Costs use only the inputs you enter. Missing inputs are never treated as zero. All values below are demo placeholders, not surveyed distances or carrier quotes.
Origin: forest loading address
Demo: landing near Rotorua
Placeholder. Replace with the real forest loading address.
Destination: Port of Tauranga log receiving facility
Demo: Port of Tauranga log facility
Placeholder. Replace with the nominated receiving facility.
Live tracking
Live tracking unavailable
No authorised tracking integration.
Route validation
Direct road, Rotorua → Tauranga
Demo: 115 km road (placeholder, not surveyed). Straight-line figures are not road distances.
Rail: Murupara → Port of Tauranga
Verified corridor (Kaingaroa Tipu article, date unchecked): about 5 Mt/yr of logs, six log trains a day, up to 900 t each. Demo rail km: 140 (placeholder, not surveyed).
Road to rail via Murupara
Demo option, unconfirmed: log loading access and commercial eligibility need KiwiRail or terminal confirmation.
Road to rail via Kawerau
Unconfirmed: the article mentions a Kawerau container terminal, not a confirmed log route.
Direct Rotorua → Tauranga freight train
Not assumed. No active service is confirmed.
Inputs (demo, ex GST)
Diesel for the fuel-only estimate: c/L (MBIE 2026w40, provisional). Fuel only, not a total.
Comparison table and cost breakdown
Route map
Unavailable. Road and rail geometry is not loaded, so no map is drawn. The straight-line truck route on the haulage card is not a transport route.
ML: not used. The project has no shipment history, so no cost, delivery or delay forecast is made.
Log Transport & Export — Master Simulator Verified / Quoted
Compares truck and rail to the Port of Tauranga, port handling, log storage, vessel loading and ocean freight. Published tariffs are used where they exist. A cost with no quote shows "Quote Required" and is never counted as zero. Rail feasibility is not confirmed for any route.

Sources & Assumptions
Port of Tauranga Principal Tariff 2026/27 (PDF). Reached 11 Oct 2026. Effective 1 Jul 2026 to 30 Jun 2027, NZD excluding GST. Used: logs wharfage $6.54/JAS m³ (security fee additional), environmental levy $0.19 bark off and $0.46 bark on per JAS m³, insurance levy $0.13 per tonne or m³ (greater of; applicability to logs to confirm), log export storage bands for Mount on-wharf and Hewlett's Road. Storage is read as cumulative weekly bands; confirm with the port.
Ocean freight, vessel charges, stevedoring, marshalling, labour and rail have no sourced rate here. Each shows Quote Required until a valid quote or invoice is entered. Live tracking is unavailable. No ML forecast is used: there is no shipment history.
