The Pharmacy Guild says GlaxoSmithKline owes pharmacies about $50,000 over a medicine recall two years ago.
A South Auckland pharmacist won a case last October against GSK over whether it should meet costs associated with the recall, and the company opted not to appeal.
But the guild says that while the costs of that pharmacy have since been met, other pharmacies' costs have not.
Chief executive Annabel Young says the guild is taking up the matter with lawyers.
GlaxoSmithKline says the court case was in relation to one pharmacy and its understanding is that there is still no legal requirement to pay pharmacists' compensation for time during a recall.
