New Zealand's Director-General of Health is not expected to name a permanent chief technology and digital officer until early July, the final peg in Chai Chuah's shake-up of executive leadership at the Ministry.

Mr Chuah has brought in Nick Robinson, a former general manager of corporate affairs at Contact Energy, to take on the chief client officer role. Mr Robinson will be in charge of client data, insights and analysis in a newly formed position that is expected to work closely with the CTO.
