The Commerce Commission has declined to grant clearance for the merger of the diagnostic laboratory (pathology) services businesses of New Zealand Diagnostic Group Limited and Sonic Healthcare (New Zealand) Limited or their subsidiaries in six District Health Board districts through the establishment of three joint venture companies. The relevant DHB districts are Hawke's Bay, Canterbury, South Canterbury, the West Coast, Otago and Southland.

Chair Paula Rebstock said that the Commission was not satisfied that the proposed acquisition would not have, or would not be likely to have, the effect of substantially lessening competition in the relevant markets.
