Just two ships bearing fuel are expected to arrive in New Zealand in the next fortnight, according to the Government’s latest fuel update, which showed overall diminishing stocks.

As of midnight Sunday, New Zealand had 48.7 days cover of petrol, down from 49.9 days last Wednesday.

It had 46.5 days cover of diesel, up from 45.5 last Wednesday and 43.4 days jet fuel, down from 44.7 days last Wednesday.

The figures include stocks both in New Zealand and on the water and destined for here.

On Monday, Prime Minister Christopher Luxon, Finance Minister Nicola Willis and Associate Energy Minister Shane Jones announced the Government would harmonise some fuel standards with Australia to encourage ships loaded with fuel to stop in New Zealand on their voyage.

“Countries that can access a wider range of shipments are better placed to keep fuel flowing,” Jones said.

Fuel refined to Australian standards was compatible with New Zealand vehicles, Jones said. The fuel also met safety and quality expectations, he added.

New Zealand would not, however, be following Australia’s lead and relaxing standards to allow higher-sulphur fuel, although the Government would monitor whether further changes to fuel specifications could open up further supply channels if necessary.

This arrangement could remain in place for up to 12 months if needed.

On Tuesday, the Government announced a temporary $50-a-week increase to the In-Work Tax Credit, which will go to a little over 140,000 households.

The change will not increase the incomes of people on a benefit, which has been controversial.

It was estimated to cost $373 million for the year. Willis has promised the cost would be met within the Government’s operating allowance.
