New Zealand's annual inflation rate is expected to surge to approximately 4% in the second quarter, marking the highest level in more than two years.
The sharp uptick is being driven primarily by soaring fuel prices, which economists estimate will account for about three-quarters of the total increase in the consumer price index.
The official data is scheduled for release Tuesday morning.
The forecast represents a significant reversal from the cooling trend seen in other major economies, where energy and commodity prices have recently dampened headline inflation.
In contrast, New Zealand faces acute pressure from elevated oil costs, which are translating directly into higher transport and energy bills for consumers and businesses.
This divergence highlights the varying impact of global energy markets on regional economies.
