Modern Zealand’s overall fuel stocks remain stable despite fluctuations in specific fuel types, according to the latest data released by the government. While petrol and jet fuel supplies have seen an increase, diesel stocks have experienced a slight dip, though officials maintain that the general supply chain remains normal.
The latest figures, collected at 11.59 p.m. Last Wednesday, indicate a 3.2-day increase in petrol and a 3.9-day increase in jet fuel. Conversely, diesel stocks saw a marginal decrease of 0.7 days. These figures account for fuel already within the country, shipments within the exclusive economic zone (up to two days away), and those further out (up to three weeks away).
Nicola Willis, speaking from Parliament, confirmed that the government will not be escalating its response level, citing the stability of the total stocks. “We continue to hear from fuel importers that they are experiencing no material issues with future shipments, which means we have the confidence to stay in phase one of our fuel response plan,” Willis said.
The stability of these fuel stocks is critical as the government continues to monitor international volatility, particularly the conflict in the Middle East, which Willis noted as a “grave” concern. The government is urging restraint and diplomatic negotiations to prevent further disruption to global energy markets.
Analyzing the Stock Breakdown
While the total figures are reassuring, a closer look at the distribution reveals a disparity between fuel arriving in the country and what is already on the ground. In-country stocks for both petrol and diesel have actually declined since the previous data collection on March 29.
Specifically, in-country petrol stocks dropped by 2.1 days, and diesel stocks fell by 4.1 days. However, jet fuel in-country rose by 3.4 days. The Ministry of Business, Innovation and Employment (MBIE) has clarified that such movements are standard, stating in a release that “fuel stocks naturally rise and fall each week as fuel is used and new shipments arrive.”
The current levels are described by MBIE as being broadly in line with the norms observed prior to recent global disruptions. The overall “cover”—the number of days the current supply would last—remains robust across the three primary categories.
| Fuel Type | Current Cover (Days) | Previous Cover (Days) |
|---|---|---|
| Petrol | 61.9 | 58.7 |
| Diesel | 51.5 | 54.5 |
| Jet Fuel | 50.1 | 46.2 |
The National Fuel Plan: Phase One vs. Phase Two
The government is currently operating under phase one of the national fuel plan. This initial stage is characterized by a focus on transparency, preparation, and the close monitoring of international supply conditions and stock levels.
The decision to maintain or change this status rests with the Fuel Security Ministerial Oversight Group, which includes senior ministers such as Nicola Willis and Shane Jones. This group evaluates several specific criteria before deciding to move to a more restrictive phase, including:
- The imposition of export restrictions on fuel.
- Significant, unexpected changes in stock levels.
- Direct advice and warnings from fuel importing companies.
- Policy shifts from the International Energy Agency or the Australian government.
- Major disruptions to the regional distribution of fuel within New Zealand.
If the government were to move to phase two, the public would still have access to fuel, but the state would issue strong advice to voluntarily reduce consumption. This would include encouraging carpooling and the use of public transport to manage demand responsibly while the government coordinates more closely with industry leaders to strengthen supply.
Market Trends and Consumer Impact
Despite the stability of the volumes, the cost of fuel remains a point of contention for New Zealanders. In recent weeks, the average price of diesel has risen to exceed that of petrol. Minister Nicola Willis acknowledged that consumers are feeling the pinch at the pump, but maintained that these price increases are consistent with trends seen in international markets.
To improve the accuracy of future responses, fuel importers have agreed to work more closely with the government by providing more detailed demand-related data. This collaboration is intended to offer the Ministerial Oversight Group a clearer picture of real-time consumption patterns, reducing the reliance on lagging indicators.
The current strategy relies heavily on the “just-in-time” nature of fuel shipments, balanced by the buffer of the exclusive economic zone and long-haul tankers. By tracking fuel in three distinct zones—domestic, near-shore, and international—the government aims to avoid the panic-buying that often accompanies fuel shortages.
The government will continue to monitor the geopolitical situation and stock levels weekly. The next scheduled update on fuel stocks will provide further insight into whether the current trend of increasing petrol and jet fuel supplies continues or if the slight dip in diesel becomes a more significant trend.
