New Zealand Oil and Gas profits have risen by $2.7 million in the past year.
The company's half-yearly results show revenue has risen from over $51 million last year to $54 million.
But a dip in production at the Kupe oil field saw a $6.6 million fall in revenue from that asset.
The Tui oil fields, however, were able to make up the shortfall, bringing in $22.7 million on 227,000 barrels sold.
