At least 10 senior bankers at ANZ Group Holdings Ltd. are leaving the firm by October, according to people familiar with the matter and an internal memo seen by Bloomberg News. This comes as the Australian lender overhauls its business under a new boss. Among those departing are Hong Kong-based John Corrin, head of corporate finance, international, and Andrew Harward, head of corporate finance, North Asia, who will both leave on Oct. 1. Singapore-based Ian Mathews, executive director for project, export and sustainable finance, will begin his gardening leave early next month.
