NZX cash trading continues to climb CASH trading on the New Zealand stock exchange accelerated for the 14th straight month in September. Total trading of $NZ3.4 billion ($A3.03 billion) in September was up 33 per cent from a year earlier and continues a trend of monthly gains since August 2012, according to NZX's shareholder metrics. Total trades climbed by 48 per cent to 107,782 for an average daily value of $NZ164 million. Share trading accounted for most of the transactions, with just 2,582 debt trades worth $NZ84 million. The stock exchange has benefited from a raft of new listings this year, including the government's partial privatisation of MightyRiverPower as well as that of petrol station chain Z Energy, dairy processor Synlait Milk, software developer Wynyard Group and search engine developer SLI Systems. A further boost to the market is expected with the government's sale of its 49 per cent stake in Meridian Energy, which is scheduled to list later this month. About $NZ312m in new capital was raised by the stock exchange's issuers in September in 23 transactions. Of that, $NZ109m was in primary equity and $NZ203m in dual and secondary equity. NZX's shares rose 0.8 per cent to $NZ1.26 and have gained 3.3 per cent this year.
