All fuel types remain above MSO minimums. Combined nationwide cover is ~49 days. MBIE assessed the situation as Phase 1 (Minor) as of 20 March 2026. 11 vessels are scheduled to arrive within 2 weeks, bringing substantial new stock.
The Strait of Hormuz disruption continues to affect crude supply to Asian refineries. Onshore petrol buffer above MSO is thin (+0.1d). The Mar 23–29 vessel window shows only 1 petrol cargo with no diesel or jet fuel — a critical gap to monitor as MBIE updates data on 25 March.
IEA activated 400M bbl collective action on 11 March 2026. NZ fulfilled obligations via oil tickets. Brent crude has stabilised around US$88/bbl after peaking near US$120.
