The Reserve Bank of New Zealand has signalled it wants to collect more data from insurers and non-bank deposit takers as it settles in to its new wider role as the regulator for these two sectors. It already regulates banks. It also announced it would redevelop its main 'Standard Statistical Return' survey of banks.Governor Graeme Wheeler told a statistics industry conference in Wellington this week that the bank wanted to strengthen its collection of data. He said the bank already collected 16,000 data sets from banks and other financial institutions, but needed to better understand the Non-Bank Deposit Taker (NBDT) and insurance industries."New standards for capital, liquidity and related party exposures inevitably require more data to be collected from the industry and may prompt a further upgrading of the [NBDT] sector's statistics in the future," he said.There were few formal statistics available for the previously loosely regulated insurance sector, he said."Consequently we're currently planning a data collection from the industry designed to meet our prudential and broader statistical needs. This is a major job as there are around 100 newly licensed insurers, and there are a wide range of potential risks to cover," he said.Wheeler also said the bank would review its 'flagship' Trade Weighted Index measure for the New Zealand dollar, which was developed 15 years ago."Since then, trading patterns have changed dramatically. In particular, China is now the largest single destination for New Zealand's merchandise exports and its exchange rate has become more flexible," he said, adding the Chinese currency is included in the bank's wider 14-currency measure of the TWI."However, we are currently undertaking a full review of all the exchange rate measures that we publish, which we hope to complete before the end of the year," he said.Wheeler added the bank was re-developing its standard statistical return for banks, which it has used for the last 15 years.Wheeler also told Statistics New Zealand officials in the audience the central bank would like a monthly, rather than quarterly, inflation measure and quarterly, rather than annual, national income figures.
