The organisation confirmed it was looking for a successor following a report in the Guernsey Press.
According to the paper, Niven, speaking at a Guernsey Finance event last week, said although there was no “end date” in sight as to when he would step down, the organisation is in the process of looking to appoint a deputy chief executive who will also act as a technical adviser.
Niven, who has held the job for five years, is also reported to have said it was important that an organisation such as Guernsey Finance “stayed fresh.”
“I’m a great believer with organisations like this that you have to refresh the chief executive on a regular basis because it needs someone to come in with fresh ideas,” he is reported to have said.
