Spark New Zealand was the most traded stock with 9.4 million shares changing hands, compared to its 3.9 million 90-day average. The stock fell 3.7 per cent to $3.75, extending yesterday's decline. The company reported increased underlying earnings yesterday as cost-cutting helped widen margins. Net profit fell without a dividend from Southern Cross.
Sky Network Television fell 2.4 per cent to $1.64, a new record-low, on a volume of 591,000. The pay-TV operator posted yet another slump in first-half earnings yesterday as it continues to shed customers and faces new competition in premium sports from Spark.
