Lawyers for Kim Dotcom have threatened to summon government spies to give evidence in court to obtain information they say they need for his compensation claim.
They have raised the possibility after the Green Party on Tuesday released a police summary of their investigation into whether the internet businessman was spied on illegally.
Mr Dotcom's lead lawyer Paul Davison, QC, told a hearing in the High Court in Auckland on Wednesday that neither he nor a court-appointed special advocate have ever been given the summary or the full report.
Mr Davison said that raises questions about what else the Crown has not disclosed.
The police investigation found the Government Communications Security Bureau (GCSB) acted illegally, but did not do so deliberately, so no charges would be laid.
The summary reveals that three GCSB agents refused to be interviewed during the investigation.
Mr Davison says in order to get full disclosure, he will consider summoning those agents to give evidence in closed court.
