‘Being the NZ MD for a European company and no local board, it can be a bit difficult to find someone to bounce ideas off to get an independent perspective. Additionally, access to best practice and business education is not always easy to find.  TEC has helped on both counts.  I have access to a pool of CEOs and their experience and I get easily digestible information from a range of informative experts.’
