COMPANY New Zealand Oil & Gas Limited (“NZOG”) is an PROFILE independent company listed on the New Zealand and Australian stock exchanges. NZOG is a founding partner in two important petroleum developments in the offshore Taranaki Basin, New Zealand – the Tui Area oil fi elds and the Kupe gas/oil fi eld – and has exploration interests in several Taranaki oil and gas prospects. NZOG is the cornerstone shareholder in a major coking coal mine project under development in New Zealand’s South Island.

New Zealand Oil & Gas Limited NZ Reg. Coy. No. WN 037 842 ARBN 003 064 962 EXECUTIVE CHAIRMAN’S REPORT

Dear Investor,

I am pleased to report to you that in the last year we have achieved signifi cant progress on the projects which will transform NZOG into a signifi cant energy producer. All three of the company’s key projects were given the development go-ahead during this 12 month period.

The Tui Area development decision was made in November 2005 with oil scheduled to fl ow from this fast- tracked development in the fi rst half of 2007. All Kupe joint venture partners agreed in June 2006 to proceed with the Kupe development which will contribute 15% of New Zealand’s gas supply once onstream in 2009. At Pike River, NZOG gave the go-ahead for development of the export coking coal mines in September 2005. Construction and fabrication activities, including the appointment of leading international construction partners, are now well advanced for each of these projects.

In addition to its key developments, NZOG is embarking on an exploration program aimed at further increasing the company’s existing petroleum reserves which, on an oil equivalent basis, stand at 13.4 million barrels. Two attractive oil opportunities identifi ed within the Tui Area permit, close to existing discoveries, will be drilled in mid-2007. The same drilling rig has also been secured for the Hector prospect, a very interesting exploration prospect to the south of the Tui discoveries.

The fi nancial result for the year ended 30 June 2006 saw NZOG record a profi t of $2.3 million (after minority interests) on revenues of $7.5 million, including a $2.5 million accounting gain in respect of NZOG’s shareholding 2 in Pike River Coal Limited and after writing off exploration costs of $0.8 million. This is a satisfactory result New Zealand Oil & Gas Limited given that the company has yet to bring its production projects on stream.

Last year’s successful share option conversion raised $43 million and was pivotal in enabling NZOG to proceed with its three developments. A further $12 million was raised through a small placement of shares and options in December 2005 and Pike River Coal Limited raised $37 million directly from two major new investors.

As signifi cant investments will continue during the 2006/2007 year, debt raisings are also in progress for both

Annual Report 2006 the Kupe and Pike River projects. The company secured a $60 million (US$37.5 million) fi nancing facility for Tui in March 2006.

The return on investment from these developments will commence with Tui in the 2007 fi nancial year, which will enjoy a high front end revenue stream, with somewhat longer time-frames for Pike River and Kupe which are both long life assets with production expected over 15-20 years.

In summary, NZOG has taken major steps in the year under review to transform itself into a signifi cant energy production company and is positioned for continued strong growth.

Tieke and Taranui Prospects

PMP 38158 NZOG 12.5% stake Tui Satellite Exploration Prospects Being Drilled The Tieke and Taranui prospects are located approximately 7 kilometres southeast and 15 kilometres northeast of Tui respectively. These Kapuni F-sand reservoir targets are similar to those discovered in the Tui Area oil fields and have potential in the event of discovery, of the order of 5-20 million barrels of oil each. Their proximity to the Tui development would provide an opportunity to quickly bring to production any discoveries made. Tieke-1 and Taranui-1 are scheduled to be drilled after the Tui development wells in the second quarter of 2007.

Further prospects (Oi and Kahu) exhibit similar subtle closures at the Kapuni F-sand level as Tieke and Taranui and provide additional potential upside in the Tui mining permit area.

Hector Prospect Hector South Sub-block

PEP 38483 NZOG stake 18.9% NZOG stake 12.5% Exploring a Potential New Oil Fairway with Substantial Upside The Hector-1 exploration well will test a dip-closed structure at the Kapuni-C level (as mapped on the 3D seismic survey of 2005) that has potential recoverable oil of 50-60 million barrels. In addition to substantial upside at this prospect, a discovery at Hector would trigger further drilling activity in this permit because it would prove a new oil migration fairway within the Taranaki Basin. Several follow-up drilling targets, such as Hector South, have already been identified in the PEP 38483 permit. During the past year a portion of the former PEP 38460 exploration permit containing the Hector South prospect was merged with PEP 38483.

Hector-1 will be drilled using the Ocean Patriot semi-submersible drill rig as part of the offshore Taranaki 10 drilling campaign. The drilling window for Hector-1 will be defined later this year, with the exact timing subject to

New Zealand Oil & Gas Limited finalisation of the Tui development installation schedule, which takes precedence. NZOG has a 18.9% interest in the PEP 38483 permit and holds 12.5% in the Hector South sub-block extension area.

Felix and Opito-Updip Area Annual Report 2006 PEP 38729 NZOG stake 75% New Seismic Survey Completed The Felix/Opito - Updip area is located at the northern end of the Kapuni Group ancient beach sands system, which was buried in the Eocene era 40 million years ago. These sandstones have formed highly prolific, proven hydrocarbon reservoirs elsewhere in the Taranaki Basin, as evidenced by the offshore Maui, Pohukura and Tui fields.

NZOG is operator of PEP 38729 and completed a refraction seismic survey in early 2006, to further define the potential of the Felix and Opito-Updip structures. Processing and integration of the seismic data together with the well information obtained from the Opito-1 well drilled in 2002 provide strong evidence for prospective trapping structures in the permit.

During August 2006, NZOG completed a coastal “transition zone” seismic survey to tie the existing onshore and offshore seismic data sets together, and to further delineate the Felix and Opito-Updip structures, including the identification of possible drilling locations. The decision on whether to drill an exploration well on the Felix or Opito-Updip structures is expected to be made in the first half of 2007 following evaluation of this new seismic data.

West Kupe

PEP38484 NZOG stake 100%

NZOG relinquished the West Kupe permit (PEP38484) during the year. This decision was made as the company was unable to obtain a time extension for drilling and after factoring in the relatively high risks associated with the Taitapa prospect, and major increases in rig costs.

New Zealand Oil & Gas Limited CORPORATE & ADMINISTRATION Share Placement: A small private placement of 13.3 million shares was made in December 2005 raising $12 million to advance NZOG’s oil and gas projects. The issue amounted to approximately 6% of the company’s issued shares.

Pan Pacific Petroleum Shares: The company subscribed for additional Pan Pacific Petroleum NL shares in a December 2005 rights issue at a cost of $3.1 million, taking its holding in Pan Pacific to 10.1%. The additional investment was made to increase the company’s exposure to the Tui Area oil fields and associated prospects. The market value of the Pan Pacific holding was $9.4 million at 30 June 2006. Annual Report 2006 Bonus Option Issue: NZOG’s free 1:2 bonus option issue to shareholders was completed during December 2005 and resulted in the issue of 107,050,236 options. These options have traded in the range of 8 to 19 cents.

FINANCIAL The company announced a surplus of $2.3 million (after minority interests) for the year ended 30 June 2006 (2005 deficit $2.6 million). The surplus was made after writing off exploration costs of $0.8 million. The result also includes a $2.5 million accounting gain in respect of NZOG’s shareholding in PRCL as a result of PRCL issuing new shares to a third party.

Total revenues for the 2006 year of $7.5 million (2005 $0.6 million) include interest income of $2.3 million (2005 $0.5 million) and a foreign exchange gain of $2.7 million (2005 loss $0.4 million). An unrealised gain of $4.1 million in the value of the company’s investment in Pan Pacific was not accounted for in the 2006 financial result.

During the year ended 30 June 2006, NZOG group invested $43 million in its three development projects: Kupe gas/oil, Tui oil and Pike River coal. At 30 June 2006 NZOG held cash of $41.7 million (including $11.3 million held by PRCL). RESERVES AND RESOURCES STATEMENT
