Relief Announced. Pressure Remains.

New Zealand has fuel. MBIE reported 46.0 days of diesel cover, including fuel on the water, as at 4 October. The pressure is on cost.

HSCM Supply Chain Stress Index

Commercial Signal

A slower rise is not a lower cost.

Diesel’s weekly increase fell from 21c to about 9c. The price still rose, and it is up about 50c in four weeks.

On the supply side, China’s approvals are about 20% below August and the IEA stock release largely re-times earlier pledges. Both help at the margin. Neither has yet shown up as cheaper replacement diesel.

Weekly changes use MBIE’s unrounded figures. The latest increase was 8.94c/L, approximately 9c/L.

Four measurement points matter:

• Series: This is MBIE’s adjusted retail price, the average price paid after discounting, not the board (advertised) price. MBIE’s diesel board price for the latest week was not available in citable form at the time of writing. The price includes GST, which GST-registered businesses can generally reclaim, and excludes Road User Charges. Actual cost depends on contract terms, discounts and surcharge arrangements.
• Dates: The observation week ended 2 October and MBIE published it on Wednesday 7 October. The next MBIE update is due on Wednesday 14 October.
• Petrol: Petrol is a separate series and is not used here. MBIE’s regular-91 board price for the latest week was not available in citable form.
• Methodology: MBIE’s importer cost and margin series include a “fuel market adjustment” applied from 27 February 2026, first noted on 23 September. Margin comparisons with earlier issues are therefore not like-for-like. MBIE did not describe its retail price series as revised.

Leading Signals vs Current Reality

1. Fuel, Energy & FX

NZ has the fuel. The question is what it costs.

MBIE’s snapshot as at 11:59pm on Sunday 4 October, published on Wednesday 7 October, reported diesel cover of:

• 29.1 days in NZ
• 2.5 days on ships inside the EEZ, within about two days of arrival
• 14.3 days on ships outside the EEZ, within about three weeks of arrival
• 46.0 days in total, across nine ships

The total includes fuel that has not yet arrived. It is not 46 days in domestic storage. MBIE said stocks were well above minimum requirements and within normal ranges, with planned orders extending about three months. The government diesel reserve at Marsden Point is separate and not counted in these figures. MBIE says it can be released to importers until 30 November 2026.

HSCM did not identify a reported physical diesel shortage in the sources reviewed. The issue shown by the data is cost.

Offshore supply: relief announced, by source

• China (Reuters, unnamed sources): Reuters reported on 9 October, citing four traders, that China is set to resume October refined-fuel exports. Two industry sources put approvals at about 3.7 Mt of diesel, gasoline and jet fuel combined, against 4.6 Mt exported in August. Reuters said Beijing normally uses a quota system but has tightened oversight by vetting shipments month by month. Energy Aspects expects the resumption to be limited, and Sparta Commodities described the volumes as lower than anticipated. China’s NDRC and Ministry of Commerce had not responded to Reuters at publication. These are approvals, not completed shipments, and the figure is not diesel alone.
• IEA and G7: The IEA’s 7 October statement says about 325 million barrels have been released under the March 2026 collective action and that releasing the remaining pledged stocks would bring about 100 million barrels to market. Members supported accelerating those releases and prioritising diesel to the extent possible. The IEA did not describe this as a separate new pledge, and no product or country breakdown has been published. HSCM’s reading is that the G7’s 100 million barrels largely correspond to these outstanding barrels, which would make them re-timed rather than additional supply. Germany’s ministry said it will take part within the volume already determined in March. Reuters, citing two sources, reported that the IEA Governing Board will decide details on 14 to 15 October.
• Russia (official): The Russian government extended to 31 October its ban on exports of diesel, marine fuel and gas oils by producers. The diesel ban for non-producers runs to 31 January 2027. On 2 October Deputy Prime Minister Alexander Novak said partial reopening could be considered if production exceeds domestic demand, while the Moscow Times reported that President Putin said on 1 October that Russia would not supply diesel to global markets until sanctions are lifted. No decision to ease was identified. This is a restriction on commercial exports, not a halt to every Russian diesel cargo.
• Hormuz and oil: Windward counted 8 transits on 8 October, down from 18 on 7 October, and reported that UKMTO had logged 16 attacks on merchant ships in the Gulf over 10 days. Counts vary with whether vessels transiting without normal AIS visibility are included. On 5 October Iranian President Pezeshkian called talks with the US “meaningless”, according to Iran International. Navigation remains severely constrained. Brent December futures settled around US$104.72 on 9 October on market-data readings (ICE settlement not verified), about 2% higher on the week, after trading between roughly US$97 and US$106. The EIA’s 6 October outlook forecasts Brent around US$105 in the fourth quarter, excluding the G7 release, and cites extreme tightness in diesel markets.

Emergency stock releases add prompt barrels. They do not by themselves add refining capacity or lift export restrictions, so they do not automatically resolve refined-diesel tightness. NZ is not a G7 member, so any benefit would reach NZ indirectly through regional and global diesel pricing, with timing uncertain.

Currency: a small recovery, not a reversal

RBNZ B1 fixings show NZD/USD at 0.56085 on 9 October, up 0.3% from 0.55915 on 2 October. It remains 0.9% below the 0.56595 recorded on 25 September. The TWI was 63.87, against 63.81 and 64.34 on those dates.

For a US$100,000 supplier invoice, before bank spreads, fees and hedges:

The week’s recovery cuts the NZD cost by NZ$542 against 2 October. The same invoice still costs NZ$1,607 more than on 25 September. Measure exposure against contracted payment dates and hedge cover, not a single headline rate.

2. Freight, Ports & Network

Asia: the indices eased, but they are not NZ rates

On the WCI, Shanghai to Los Angeles fell 3% to US$7,624 and Shanghai to New York fell 2% to US$10,220. Drewry counted 4 Transpacific blank sailings announced for next week, down from 11 this week, and 6 on Asia-Europe, up from 5. It said carriers are trying higher FAK rates for the second half of October and expects rates to remain stable next week.

The WCI is a global East-West benchmark. The Intra-Asia index covers a different set of regional trades and is context for NZ cargo that connects through Asian hubs. Neither is a China-to-NZ or Oceania rate, and HSCM does not infer that NZ quotations fell by 1% or 2%.

HSCM did not identify a new Oceanbridge, Navia or carrier advisory for NZ trades in the sources reviewed. The latest NZ-specific references remain Oceanbridge’s 23 September guidance to book Asia imports three to four weeks ahead, with pre-Christmas cargo-ready dates of 30 October for feeder ports and 6 November for direct ports, and Navia’s September snapshot of about US$2,634/TEU from Shanghai, excluding surcharges and local charges.

Domestic network

Kaitaki resumed Cook Strait sailings on 26 September, restoring the two-ship Interislander pattern. HSCM did not identify a reported disruption in the sources reviewed, but this issue does not assess day-to-day service performance. A published timetable is not verified execution. Check live Interislander and Bluebridge service status for time-critical freight, and NZTA’s Journey Planner before dispatch.

Port of Auckland’s full import/export container FAF rose from NZ$15.00 to NZ$17.50 on 9 October, an increase of NZ$2.50 per container or 16.7%. The port applies the tier in force on the vessel’s arrival date. This is a change to a port fuel-adjustment charge, not a 16.7% increase in total container freight or landed cost.

3. Demand, Trade & Dairy

Survey strength is not yet realised activity

August’s PMI was 53.1 with new orders at 54.9. The PSI was 51.2 with new orders at 55.2, but services activity/sales were 49.4. August retail card spending fell 0.9%.

ANZ’s September Business Outlook recorded confidence of 51.9, expected own activity of 47.9, reported activity of 10.8, cost expectations of 81.9 and pricing intentions of 48.4. Firms expect higher costs while fewer plan to raise prices. That is a planning warning, not a measured margin decline.

August consents rose 5.6% seasonally adjusted, taking the annual total to 41,268 new dwellings, up 21%. A consent is not a materials order. Project starts, financing and contractor capacity decide when the pipeline becomes demand.

Keep inventory selective. Tie additional commitments to confirmed orders and SKU velocity, and challenge broad contingency stock built for the one-ship Cook Strait period, but only against actual service performance.

Dairy

GDT Event 413 on 6 October lifted the price index 1.2%, with an average winning price of US$3,928/t. Skim milk powder rose 4.3% and whole milk powder 1.2%, while butter fell 0.3%, anhydrous milk fat 1.1% and cheddar 3.7%. Fonterra’s 2026/27 midpoint remains NZ$9.50/kgMS, with a range of NZ$8.50 to NZ$10.50, and HSCM did not identify a revision. The next GDT event trades on 20 October.

4. Rates & Compliance

Rates: policy, signals, market pricing and bank views

• Policy: The OCR is 2.75%, raised on 2 September. The next decision is the Monetary Policy Review on 28 October. The next full Monetary Policy Statement is on 9 December.
• RBNZ signals: The September statement projected annual CPI of 3.9% for both the September and December quarters. FXStreet notes that its projected December-quarter average OCR of 2.81% is consistent with no move in October and a hike in December.
• Market pricing: FXStreet, citing Reuters, put the chance of a 25bp hike on 28 October at about 58% as at 6 October, down from about 80% in late September, with a December increase fully priced. Another measure, centralbank.watch (undated, based on bank-bill futures), showed 88% for no change. Methods and dates differ, and none is an RBNZ decision.
• Bank views: Westpac expects a pause on 28 October and a hike to 3.00% on 9 December. FXStreet reported on 6 October that BNZ expects a 25bp rise in October. HSCM did not verify updated views from ANZ, ASB or Kiwibank.
• HSCM planning: HSCM does not forecast the decision. Test inventory and financing assumptions under both a hold and a 25bp hike, with NZD/USD near current levels. September-quarter CPI is due on Thursday 22 October.

NZ-India FTA enters into force on 20 October

MFAT confirms the agreement has been ratified. Trade Minister Todd McClay said 57% of NZ exports to India will be tariff-free from day one, including wool and more than 95% of forestry and wood exports, with a second round of cuts on 1 January 2027. India says 100% of Indian exports to NZ become duty-free from day one. Confirm HS codes, rules of origin, evidence and customs-entry timing before claiming preference. HSCM did not verify Customs or NZTE operational guidance.

BMSB

The 2026/27 season is active. MPI’s exception for goods in a fully enclosed container sealed before 1 September applied only to containers exported before 1 October, so shipments exported from 1 October no longer qualify. Hold the sealing evidence for anything that relied on it. HSCM did not identify a publicly reported enforcement action in the sources reviewed. That is not proof that none has occurred.

US lamb safeguard

The USITC injury hearing is on 16 October at 9:30am Washington time, about 2:30am on Saturday 17 October NZ time, with a prehearing conference on 15 October if the Commission deems it necessary. Post-hearing briefs are due 23 October and the injury determination by 13 November. A remedy hearing would follow on 1 December if the finding is affirmative or split, with the report to the President by 11 January 2027. NZ sheepmeat exports to the US are worth about NZ$685m. On 6 October, 68 members of Congress signed a letter backing an affirmative finding. This is a trade-policy risk, not a confirmed new tariff.

What Smart Operators Are Doing Now

• Recalculating the next replenishment. Update fuel, freight, surcharge and exchange-rate assumptions using the dates and terms that apply to actual orders, not the last purchase order.
• Auditing fuel surcharges. Check the benchmark, reset date, lag, floors and caps, and whether reductions pass through as quickly as increases. Use diesel, not petrol, as the benchmark.
• Quantifying FX exposure. List unhedged USD commitments, settlement dates and price-validity periods, and stress-test at 0.56 and below. Discuss hedging with the bank or a treasury adviser.
• Protecting critical lanes. Book against forwarder guidance, confirm equipment and routing, and separate must-arrive lines from replenishment that can tolerate a rollover.
• Keeping inventory selective. Prioritise critical SKUs, confirmed demand and supplier reliability, and avoid assuming a lower index has reduced the cost of a shipment.
• Preparing documentation. Confirm India FTA classification and origin evidence before 20 October, and BMSB evidence for any shipment that relied on the exception.

HSCM Base Case

Relief is announced, not yet delivered.

Diesel is still rising, more slowly. China’s reported restart is a monthly quota below August’s volume. The IEA is accelerating the remaining balance of its March commitment, while the precise relationship to the G7 announcement and the diesel allocation remains to be confirmed. Hormuz navigation remains severely constrained. The mechanisms supporting refined-product pressure have not yet normalised. The NZ dollar recovered slightly and the Drewry indices eased, but NZ-specific freight evidence remains limited. Demand is constructive but mixed, and HSCM did not identify a verified domestic freight disruption.

These scenarios are planning tools, not forecasts or predictions of any RBNZ decision:

Relief case: If China’s approvals continue, the IEA release is diesel-heavy and quick, and Hormuz transits recover, diesel premiums could ease and NZ pump prices could begin falling with a lag.

Middle case: If the releases arrive but Russian and Chinese constraints persist, diesel could stay elevated and volatile, with surcharges slow to fall.

Stress case: If attacks on shipping continue, China’s approvals tighten or Russia’s restriction is extended, product premiums, tanker costs and USD fuel costs could rise together.

Key Triggers

• MBIE diesel, 14 October: another rise or the first decline.
• IEA, 14 to 15 October: the diesel share, country allocation and delivery timing.
• China: whether monthly approvals continue into November.
• Russia: whether the 31 October producer restriction is renewed.
• Hormuz: transit counts and reported attacks.
• NZD/USD: a sustained move below 0.55.
• Rates: September-quarter CPI on 22 October and the RBNZ decision on 28 October.

Dates to Watch

• 14 October: MBIE weekly fuel price and fuel-stock update (Wednesday afternoon)
• 14 to 15 October: IEA Governing Board meeting on release details
• 15 October: Drewry WCI; USITC prehearing conference (if held)
• 16 October: USITC lamb injury hearing, 9:30am Washington (about 2:30am Saturday 17 October NZ time)
• 20 October: NZ-India FTA enters into force; GDT Event 414 trades
• 22 October: Stats NZ September-quarter CPI
• 23 October: USITC post-hearing briefs due
• 28 October: RBNZ Monetary Policy Review
• 31 October: Russian producer diesel, marine fuel and gas oil export ban scheduled to expire
• 4 November: Stats NZ labour market statistics, September quarter
• 7 November: NZ general election
• 13 November: USITC lamb injury determination due
• 30 November: Last day the government diesel reserve can be released to importers

The Week in Context

Last week, the dominant signal was accelerating landed-cost pressure. This week the picture is more nuanced.

Diesel is still rising, but more slowly. The NZ dollar has recovered slightly. Both Drewry indices have eased. China has reportedly restarted exports and the IEA is accelerating stock releases. Those are welcome developments.

But diesel is about 130c/L above its pre-conflict level, China’s approvals are about 20% below August, the IEA is accelerating the remaining balance of its March commitment, with the G7 relationship and diesel allocation still to be confirmed, and Hormuz transits fell further. NZ has adequate reported fuel stocks and improved scheduled Cook Strait capacity. Lower landed costs have yet to follow.

The distinction for the coming week is between relief announced, relief delivered and relief reflected in landed cost. That is where operators should focus.

The weekly increase has slowed. The cost reset is not over.
