ASB’s Q2 2026 Regional Economic Scoreboard left Wellington joint last with Gisborne while Canterbury led on dairy cash, jobs and retail. The capital’s multi-quarter underperformance is structural: public-service consolidation, a deep housing correction and stalled population growth colliding with a national OCR still set for nationwide inflation.

New Zealand imports every litre of liquid fuel after the permanent closure of the Marsden Point refinery. Regular tanker arrivals from Singapore and other hubs continue without reported issues.

Importers hold confirmed orders that provide visibility through to late June and planned orders into early August. MBIE receives continuous updates from fuel companies and has seen no reports of disrupted supply chains.
The country remains in Phase 1 of the National Fuel Response Plan 2026. Supply is stable and no change in purchasing behaviour is required.
Costs still feeding through to households and businesses
Higher transport costs from diesel and jet fuel still feed into business operating expenses across logistics, agriculture, construction and tourism. These costs ultimately reach households through goods prices and airfares.
The regulatory minimum stockholding obligation, introduced in January 2025, adds compliance costs for importers yet current holdings remain well above the thresholds. Market signals continue to drive orderly resupply despite the added layer of rules.
With confirmed orders secured and Phase 1 status holding, pump-price volatility is expected to stay contained in the near term.
