Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.
Two separate scales from 1 to 10. Strature never multiplies or merges them.
Why it matters
Earth Sciences New Zealand expects a Very Strong El Niño, with spring drier than normal in the north and east of both islands. In March 2025 ministers classified drought across five regions at once; this card asks whether that recurs by 30 Jun 2027.
Why Likelihood 6 Recurring: once in 36 months, so not below 3. Pushes: a Very Strong El Niño expected into autumn 2027; a dry spring outlook in the east; dry soils in July. Brakes: El Niño explains only part of the weather; the west of the South Island is expected wet.
Why Impact 4 Threshold case three regions classified at once.
The other facts on file (5)
- Earth Sciences New Zealand declared El Niño conditions with an 80% chance of reaching strong intensity in July-September; rain near or below normal in the north and east of the South Island and the east of the North Island [1] (2 Jul 2026)
- Earth Sciences New Zealand expects a Very Strong El Niño, peaking perhaps in November or December 2026, neutral not before April-May 2027; spring drier than normal in the north and east of both islands; higher wildfire risk in Canterbury, Otago and Marlborough [4] (2 Sep 2026)
- September-November 2026 outlook: below-normal rain most likely in the east of the North Island; soil moisture near or below normal in the east and north of both islands; above-normal rain likely in the west of the South Island [5] (2 Sep 2026)
- Some places in meteorological drought, with warning signs in Mid Canterbury, East Otago and around Dunedin; Chris Brandolino: each El Niño has its own personality [2] (7 Jul 2026)
- Northland, Waikato, Manawatū-Whanganui, Marlborough and Tasman classified a medium-scale adverse event, after Taranaki in February [3] (7 Mar 2025)
Where it sits
How it spreads
Sample, no data on file. No cited flows by country on file for this risk.
Between 3 Nov 2026 and 30 Jun 2027, ministers classify drought as a medium- or large-scale adverse event covering three or more New Zealand regions at once, as shown in a Ministry for Primary Industries or ministerial release.
Not under wayChannels 3 on the card
- CanadaNo Canadian loss sourced.
- Dairy and meatA broad drought cuts milk volumes, forces stock sales and lifts food prices (Strature's view).
- Power and fireA dry summer lowers hydro lakes (Strature's view); the agency named Canterbury, Otago and Marlborough for higher wildfire risk [4].

Three scenarios and their signposts
- S1
Patchy dry
Drought is classified in one or two regions only.
- S2
Broad drought
Three or more regions are classified by late summer, as in 2025.
- S3
El Niño fades early
Autumn rain arrives.
| Path | Signpost |
|---|---|
| S1 | Summer rain in Canterbury and Otago near normal |
| S2 | A classification for an east-coast region by February 2027 |
| S3 | The agency's outlook moving to neutral before April 2027 |
No probability is given for the three paths.

The other side
Farmers who planned feed and water early after the July warnings [2] can keep stock and gain when prices rise (Strature's view).
