It said there had been a “slight decrease across all fuel types since the last update on 8 April”.
“Movements remain within expectations and show normal patterns.”
The previous update, which was accurate to the night of Sunday, April 5, showed New Zealand had 28.3 days of petrol in-country, 23.7 days of diesel and 27.9 days of jet fuel.
With the on-water fuel counted, there was 62.6 days’ worth of petrol, 51.7 days’ worth of diesel and 53.5 days’ worth of jet fuel.
Earlier on Monday, Prime Minister Christopher Luxon relayed that fuel importers were “highly confident” about future orders, telling Newstalk ZB’s Mike Hosking Breakfast that they had orders going into mid-May and beyond.
“Their refineries are finding alternative sources of crude. It is coming at a price, obviously, which is a challenge for everybody, we get that, but my god, if we lose supply, that’s the biggest problem we’ve got,” Luxon said.
While a ceasefire was announced last week between the US and Iran, peace talks over the weekend mediated by Pakistan didn’t lead to a formal agreement.
On Monday morning (NZT), US President Donald Trump ordered the US Navy to implement a blockade of the Strait of Hormuz shipping lane.
That is the strait of water through which about 20% of the world’s oil flows on its way to refineries, including those that service fuel to New Zealand.
