The churn in the highest ranks at National Australia Bank may abate, with the selection of three new faces for the bank's management committee. The new CTO and new chief lawyer bring an abundance of recent, relevant experience, while the third new face - a former state premier picked to run NAB's institutional banking - brings colour and controversy along with conjecture they may be a future CEO.Patrick Wright, from Barclaycard, is the big name hire and the most significant of the three executives announced yesterday.The other two are Sharon Cook, the new chief legal and commercial counsel and Mike Baird, new chief customer officer, corporate and institutional banking.Wright and Baird fill jobs that have seen frequent turnover at NAB, while Cook's post is said to be "a new role".Andrew Thorburn, NAB's managing director, said it took two world tours to turn up Patrick Wright, now the global COO of Barclaycard.The CV for Wright shared by NAB related one highlight of his early career as head of retail operations at JP Morgan Chase in the US.In 2008, Wright crossed to Wincor Nixdorf as US President and CEO. He may have crossed paths with reformist Australian bankers in that job; Wincor Nixdorf was a key supplier to Commonwealth Bank for its Albert point of sale tablet.Prior to joining Barclaycard US in 2012, Wright was the founder of Tuyet Consulting, an advisory firm "'established to assist financial institutions in maximising operational resources."Thorburn told a media call yesterday Wright has "done a lot of transformations, robotics and digitisation of the bank."At NAB, Wright will oversee the IT overhaul formerly known as NextGen, a term retired from the bank's lexicon over the last couple of years, and one indicator this long running project is a problem child.A second hire - that of the former conservative New South Wales premier Mike Baird - is the one attracting the most comment over the past day.Baird's experience is now a little dated, given it is ten years since he left the banking industry for provincial politics.Still, NAB set out his banking career as: head of debt capital markets originations for NAB (having joined the bank, post uni, in 1989), then head of corporate and institutional Banking with HSBC in Australia and New Zealand and lastly a global relationship manager in corporate finance with Deutsche Bank.?His political counsel may be valuable too, with Baird taking care on the media call to repeat lines about banks "reconnecting" with and "understanding" customers.Thorburn, as chair of the Australian Bankers Association, played a big hand in the selection of Anna Bligh, a former Labor premier of Queensland, as CEO of the ABA.Cook joins NAB from King & Wood Mallesons, where she is the firm's managing partner, clients. Cook was managing partner of Henry Davis York - a firm specialising in banking and financial services - from 2008 until 2014.
