WHILE Brierley Investments Ltd (BIL) will always maintain exposure in the Untied States and Britain, progressively the New Zealand group is looking to become more regionally-based, with interests at home, in Australia and Asia. Last year, a new director was appointed to the board in Auckland, with special responsibility for Asia. Mr Stephen Temple, managing director of BIL Group Treasury limited (Hongkong branch) explained that an increasing focus on Asia was encouraged by two factors; lower interest rates in Australia and New Zealand and high growth rates in Asia. Mr Temple explained the investment strategy. ''Assets are diversified by investing in relatively small projects such as joint ventures, local property and so on,'' he said. BIL's financial management principles call for financial conservatism, asset liquidity and maintaining a strong credit rating. Cautious investors and business partners tend to be large, well-established and stable. The Singapore Government is now the largest single shareholder of BIL. ''As we don't have China experience we will be choosing business partners extremely carefully,'' Mr Temple said. Although the group has substantial investments in the US, Mr Temple can see a time when it will pull out completely. BIL concentrates on three areas; Air New Zealand, Carter Holt Harvey - concerned with forestry and fishing - and Sealord, the Maori joint venture which has the biggest fishing quota in New Zealand. The three are export-orientated and all have very high export receipts for Asia. Sealord for example, sell 40 to 50 per cent of their catch to Asia. In the current fiscal year, the company hopes to retain conservative debt levels, keep profit levels at the same rate as last fiscal year - NZ$251.1 million, (HK$7.89 million).
