A detective has denied he accused Quinton Winders' father of masterminding road worker George Taiaroa's murder.
Detective Andy Livingstone was responding to a claim that Max Winders made in the High Court at Rotorua, where his son is on trial for the murder.
Mr Taiaroa was shot while in charge of a stop-go sign at a road construction site near Atiamuri on March 19, 2013.
Det Livingstone said on Wednesday that DVD recordings of two interviews he conducted with Mr Winders proved he hadn't made the mastermind allegation.
Pressed by defence lawyer Jonathan Temm, he denied he had said something along those lines because senior officers had ordered pressure be put on the Winders family.
Earlier, Det Livingstone said he found a green gun case with ammunition wrapped in it while searching a scrubby area on a property at Benneydale where Quinton Winders did fencing work.
He said the case was damp and mouldy, both inside and out.
When Winders' mother, Janet, gave evidence on Monday, she said she had bought her son a green gun case on a trip to Britain.
