TV3 presenter John Campbell and a Campbell Live producer have been summonsed as witnesses for the Waiouru Army Museum medals burglary depositions hearing.
Police have also filed an application for an order to compel Campbell and producer Ingrid Leary to answer questions disclosing the identity of an informant.
MediaWorks TV, which owns and operates TV3, will oppose the application, it said today.
TV3 will almost certainly argue "privilege" in terms of the media's right to withhold the identity of informants.
Two men, aged 37 and 39, who have name suppression, have been charged with the burglary of the museum.
