We are a far more diverse and complex society than we used to be. Globalisation, stronger international linkages, migration inflows from a very wide range of countries and cultures, the introduction of MMP, widespread and fast adoption of new digital technologies; these are just some of the developments which mean a radically different operating environment for our public services. This diversification raises the question of whether our public service workforce is diverse enough to meet the challenge of successfully providing citizen-centric services for more diverse communities. Growing diversity also poses questions for our ethics and integrity systems. New Zealand has a well-deserved reputation for high standards of integrity in public life. But our standards and practices, our 'culture' of integrity, was developed when we were a much smaller, self-contained and homogeneous society than we are now. We canâ€Ÿt take it for granted and we expect that our work as chief executives, and our discussions with Ministers, will increasingly emphasise the need to maintain integrity as a cornerstone of the trustworthiness of the system.
