The younger brother of a Blenheim Mongrel Mob member sent text messages saying his "bark is real", that he was prepared to kill to earn a patch.
Evidence at the trial in the Nelson District Court of James Kiriona, his younger brother Joshua Kiriona, Daniel Minogue, and Tuwhare Pui, who are accused of violently robbing a Canvastown home for drugs and cash, has centred around text messages between the parties before and after the September 2012 "rip".
Defence lawyers for each of the accused have denied all charges, which include aggravated robbery and wounding with intent to cause grievous bodily harm.
The Crown says text messages between the Kiriona brothers indicate that the younger, Joshua, was keen to do violence to gain entry into the Mongrel Mob.
"Sieg heil my mighty. Give me a bark, I'll just start breaking limbs," read one message from Josh to James.
"My bark is real, I'll kill mother f.......
"Sieg. I want to get my colours as soon as possible."
During the opening day of the trial, Crown prosecutor Mark O'Donoghue said Reginald "Reg" Mischeski's property was "hit" by Joshua Kiriona, Pui and Minogue at the order of James Kiriona on behalf of the Blenheim Mongrel Mob.
Intercepted text messages from before the robbery, sent from James to Joshua Kiriona, suggest that James had been ripped-off by Mr Mischeski in the past and he was due for revenge or "makutu", O'Donoghue said.
He said James instructed his younger brother to "rip Reg".
Defence lawyer Rennie Gould said James Kiriona was an old friend of Mischeski and that he was distressed to learn he had been put in hospital.
She said he didn't order any "hit" or "rip".
O'Donoghue said further text messages suggested the Kiriona's intended to keep some of the spoils of the robbery, against the wishes of the captain of the Blenheim Mongrel Mob chapter.
"There has been a massive double-cross, against Reg and possibly against the captain of the Blenheim Mongrel Mob," he said.
Under cross-examination by Hamish Riddoch, defence lawyer for Minogue, Hayley Kramer, co-owner of the house, said neither she nor Reg were Mongrel Mob members.
She said the man who punched her and kicked her in the stomach used a Mongrel Mob hand signal - a clenched fist with with the thumb and pinky fingers extended - which she recognised through common knowledge.
"[The Mongrel Mob] are pretty much a part of Marlborough now," she said.
Though she had previously met the Kiriona brothers, she did not know if they associated with the gang.
She conceded that Mischeski sometimes smoked cannabis and had previously used methamphetamine, which he would acquire from friends who could have been Mongrel Mob members.
The trial is set to continue into next week.
