Xero, which publishes cloud-based software for small businesses, has named new managing directors for New Zealand and Australia. The two countries are the New Zealand company's biggest markets with Australia taking over No. 1 from the home country in the last two years. Anna Curzon became New Zealand managing director at the end of 2015 when Victoria Crone resigned to run for mayor of Auckland. Xero also said Trent Innis will replace Chris Ridd, who led the Aussie business for five years.
