Tight suppression orders surround the men allegedly kidnapped, one of them the businessman. Those closely associated with them also have their identities protected.
In a lengthy opening, Crown prosecutor Ngaroma Tahana told how Dwyer became "inflamed" after learning his girlfriend was in hospital because she'd been injured by a broken sex toy while on the rich man's launch.
Dwyer called in reinforcements and plans were hatched to extract revenge by extracting a large amount of property from him, including his boat, expensive cars and items from properties he owned.
After his girlfriend was robbed of her cellphone the businessman instructed a friend to load a truck with goods from a Mt Maunganui shed, but as he was doing so, he was cornered, beaten and forced to drive towards Rotorua.
Daly had pulled out a handgun, Ms Tahana said, at one point firing it through an open window. The victim had also been threatened with a hammer.
At Rotorua he was choked unconscious, punched when he came to and had a pistol pushed in his mouth.
The businessman was attacked at his lakes property where Dwyer hit him in the head with a rifle butt.
Forced to his central North Island farm he was repeatedly threatened with firearms and forced to withdraw $10,000 from his business account. En route to Rotorua to make further withdrawals he fled while gassing up his car, thumbing a lift to the police station. His friend was set free near Tauranga.
