The New Zealand fire service is reporting that the BNZ's regional headquarters on the Wellington waterfront is one of the two buildings in the city that have sustained the most damage in the 7.5 earthquake that struck at midnight last night. The NAB owned bank's HQ was shut for months following damage in a less severe series of earthquakes in 2013. Civil defence authorities around the lower North Island and upper South Island are still working to determine the amount of property damage from last night's earthquake. National Australia Bank shared some data on customer's use of digital banking in PR for a modernised mobile banking application finally ready for iOS devices. NAB recorded more than 50 million internet banking logins across its digital platforms monthly, of which around 70 per cent are via mobile devices, the bank said. There are more than 1.7 million active mobile banking users, NAB said. Six names may be kicking tyres on ANZ's wealth business, an entity formally placed on the market by the bank earlier this month.
