Great South Basin oil and gas quest set to begin
The economies of Southland and Otago are to get a major boost from oil and gas exploration, as international investors prepare to spend more than a billion dollars exploring the vast Great South Basin over the next five years, according to Associate Energy Minister Harry Duynhoven.
"The intensity of work proposed for the Great South Basin is unprecedented in New Zealand’s history and will effectively double the amount of investment in oil and gas exploration here over the next few years," Harry Duynhoven said.
The government announced today that oil and gas exploration permits for four areas of the Great South Basin (in the southern oceans off Southland) have been awarded to two major groups of investors:
- A consortium led by ExxonMobil New Zealand (Exploration) Limited (USA) which includes local company Todd Exploration Limited (New Zealand)
- A consortium led by OMV New Zealand Limited (Austria) which includes PTTEP Offshore Investment Company Ltd (Thailand), Mitsui Exploration and Production Australia Pty Ltd (Japan)
Harry Duynhoven said the interest of major international oil companies indicated the high potential of the basin.
"It is one of world’s hot spots for exploration. The data indicates the potential for commercially viable finds, which could have significant future benefits to New Zealand."
Mr Duynhoven said oil companies were expected to spend $1.2 billion exploring the Great South Basin, and a share of that money would be spent in the southern region.
Energy Minister David Parker said the work assisted the government's energy goals. "Assuming exploration success, the country stands to earn significant revenue from royalties and taxes flowing from this investment, and it will assist in ensuring security of energy supply."
"Although the world is working to lessen
its reliance on fossil fuels, we will be dependent on oil
and gas for some time to come. It is in our economic
interest that the oil we use comes from local sources if
"As with other fossil fuels, it is important that New Zealand take responsibility for the greenhouse gas emissions that come from its use here, just as Japan does for the emissions that come from coal they import from New Zealand."

Great South Basin – Questions and Answers
Where is the Great South Basin?
The Great South Basin lies offshore from the coast of Southland and south Otago, and at over 500,000 sq km is one of New Zealand’s largest petroleum basins (covering an area 1.5 times New Zealand’s land mass). The current area of awarded permits covers 18% of the basin.
What is the potential of the Great South Basin?
The basin has only been very lightly explored, so until recently, little has been known about the geology and prospectivity of the basin.
Recent data indicates that the Great South Basin may have the greatest petroleum volume potential of all New Zealand’s basins. In particular it has the thick sediments required to produce hydrocarbons, favourable reservoir and source rocks, and is not affected by large scale seismic faulting found in most New Zealand basins.
How does the potential of the Great South Basin compare with Maui?
Maui is about 3.8 trillion cubic feet of gas in size, and has produced approximately 225 million barrels of oil. Data for the Great South Basin indicates the possibility for potential of up to ten times those figures - but this is, at this stage, unproven.
What does this mean for Southland's economy?
For support services alone, the financial benefit to Southland is in the order of tens of millions of dollars. If a significant oil and gas strike follows, the financial return to the region would be in the order of billions of dollars of direct investment. A commercially viable find would create a building and job boom.
The economic impacts of oil and gas exploration in Taranaki offer a possible point of comparison. A recent Business and Economic Research Limited economic study found that last year the oil and gas industry contributed $733 million to that region’s GDP, which is close to 17 percent of total regional GDP, and employed approximately 773 people. When including indirect and induced impacts, the oil and gas industry contributed $1.41 billion in regional GDP and employed over 3100 full time equivalents.
How many bids were received?
Five bids were received.
A large number of companies from around the world took interest up to the final stages of the tender round. Many expressed strong interest in future development of the basin, and it is possible that as new data becomes available they will seek interests in the remaining areas of the basin.
How were the bids evaluated?
Technical evaluation of bids comprised a detailed quantitative and qualitative process which involved scoring information provided by bidders. Bidders also made an oral presentation to support their bid documentation and any information provided in this way was incorporated in the final evaluation and scoring of bids. The same process was used to evaluate the comparative merits of overlapping bids.
With this blocks offer attracting a high level of interest from both domestic and international companies, additional, more stringent, procedures were put in place to mitigate risks associated with any review of the evaluation and decision making process. These more stringent requirements included the establishment of an Evaluation Team, a Steering Group and the engagement of Queens Council to ensure that the process was robust. Based on this process, officials made recommendations to Ministers who then made the final decisions.
How soon will drilling start? What is the timeline?
It is likely to be at least four years before any of the companies awarded permits will know if there is a commercially viable amount of oil or gas in their permit areas, and then another 10 years before that oil or gas reaches the market.
The exploration is likely to follow these steps:
Identify oil and gas targets First
phase done as part of the bidding process
Confirm the targets with seismic data In the next 2-3 years
Start test drilling 3-5 years from now
Evaluate and appraise any discovery 2-5 years from initial discovery
Make the decision whether or not to develop any discovery 2-5 years from initial discovery
Make the decision whether or not to award a mining permit 2-5 years from initial discovery
Then, assuming a discovery is economically viable, the production of the first commercial oil or gas 10 years + following discovery
If significant oil and gas is found, won't it all go offshore?
If commercially viable quantities of oil and gas are found, it would be sold primarily overseas. However, if there's any threat to supply for New Zealand, New Zealand has the right to retain enough oil for our needs and so we would be able to order some of the oil directly to the Marsden Point refinery. In that case we would still pay the market price.
What will happen to the other 82% of the Great South Basin not covered by the awarded permits?
It's intended that they will be opened up for future exploration. But there is less information available in those areas. Exploration companies and the government will be waiting to see the results of the exploration which are about to start before deciding what to do with the rest of the basin. There is no doubt that a commercial discovery in the permitted areas would encourage further seismic acquisition and exploration in other areas of the basin.
Who pays for the exploration?
The companies which own the permits pay, and take all the risks. There is no risk to the New Zealand taxpayer.
What role does the Government play in the exploration of the GSB?
In April 2006 the government, in an effort to promote and manage petroleum exploration activities in the basin, commissioned an extensive seismic survey (known as the DUN-06 survey) of the northern section of the basin. This survey was part of the government’s efforts to acquire data under a $15 million fund established in 2004 to lift petroleum exploration in New Zealand. The data was then offered freely to explorers to promote and encourage exploration in the hope that it would lead to the discovery of new petroleum reserves.
Other exploration initiatives
introduced by the government in 2004 included:
- Adjustments to tax provisions
- Reductions in royalty rates for new discoveries made before 31 December 2009
- Additional funding to promote investment in New Zealand
