The sinking of the Rena has contributed to the ongoing debate about whether New Zealand should seek to capitalise on its untapped petroleum reserves. There is a perception that foreign exploration companies provide little or no benefit to the economy while threatening our environment.
The truth is that the contribution of the oil and gas to our economy is more significant than most people realise. While it is broadly understood that a discovery will result in petroleum miners paying royalties to the Crown, there is confusion over the true level of royalties payable.
Royalties are only one portion of the industry's economic contribution to the economy. We also make a substantial contribution to the corporate and employee tax base, as well as to the wider economy in terms of employment and infrastructure development.
The Ministry of Economic Development estimates that the Government receives around 42 per cent of an oil company's profits in corporate taxes and royalties. Petroleum miners pay a royalty in respect of producing wells. This is the higher of an ad valorem royalty, based on 5 per cent of gross sales value, or a royalty based on 20 per cent of "accounting profits". For virtually all of New Zealand's producing offshore O&G fields, the 20 per cent accounting profits royalty far exceeds the 5 per cent ad valorem royalty.
In addition, the accounting profits royalty is often much higher than 20 per cent of the true reported accounting profit. This is because "accounting profits" is a defined term for royalty purposes but the definition bears little resemblance to "profit" as that term is generally understood.
