New Zealand's financial regulator is refusing to reveal exactly what it spent investigating Milford Asset Management and one of its traders for alleged market manipulation, claiming the costs in the case are "sensitive" and their disclosure possibly prejudicial.
Milford last month paid $1.5 million in a settlement following a Financial Markets Authority probe, $1.1 million of which will go to the Crown, with the balance covering the costs of the regulator's investigation.
One of Milford's portfolio managers is still facing enforcement action.
Milford portfolio manager Mark Warminger ceased to be involved with the firm's investment team, without explanation, last month.
The company last month would not comment on whether Warminger was the individual still under investigation by the FMA.
