Canadian oil company TAG has found more oil and gas in Taranaki.
The company says its Sidewinder-2 onshore well near Inglewood struck oil at a dept of 1,597 metres.
It is the company's third find in five months in Taranaki.
Chief executive Garth Johnson says the well extends the area of last November's Sidewinder-1 discovery, and adds five separate oil-and-gas-charged zones.
Mr Johnson says the company's drillers have only begun exploiting the area.
The new find will be flow-tested ready for the Sidewinder production station due to be built by mid-2011.
Another well will begin immediately. The company anticipates boosting production through multiple discoveries in the Taranaki Basin via high-impact exploration drilling.
