Haile and the resumption of operations at Didipio in Philippines were the highlights of a quarter that on a consolidated basis produced 79,177oz at all-in sustaining costs of US$1218 per ounce - on sales of 97,445oz.
That took the first nine months output to 256,216oz.
Full year guidance of of 350,000-370,000oz at AISC of $1200-1250/oz sold was reaffirmed.
Production from New Zealand was impacted by the nation-wide COVID shutdown.
At the end of the third quarter, OceanaGold had available liquidity of $143.2 million including $113.2 million in cash.
The company's net debt position was $256.5 million, an increase from the previous quarter of $224.8 million as increased capital expenditures were partially offset by higher sales.
Recently appointed acting CEO Scott Sullivan said he was "pleased" with the third quarter performance while acknowledging the company had "work to do to regain market credibility".
Shares in OceanaGold were at A$2.55 this week in Australia, capitalising the company at $1.8 billion.
The stock has halved in market value over the past few years, with difficulties at the relatively new Haile development and the unexpected forced closure of Didipio the two big negatives.
