The New Zealand division of ExxonMobil lifted its net operating profit 57 per cent in 2017 as revenues rose on higher volumes.
The local company's net profit from continuing operations for the year to December 2017 was $143.3 million, up from $91.2m in the prior year, financial statements lodged with the Companies Office show.
Revenue rose to $2.68 billion versus $2.20b in the prior year "in what continues to be a challenge and competitive marketplace," ExxonMobil's NZ directors said in their report.
ExxonMobil NZ's spending on raw materials and consumables lifted 19.5 per cent to $1.59b, while it paid $641m in sales tax and duties, a 5.6 per cent lift on the year earlier.
Inventories lifted to $349m versus $320m in the prior year. Global oil prices are gradually recovering and are now at their highest level since November 2014 with brent crude around $80 a barrel and West Texas Intermediate (WTI) around $71 per barrel.
