Prosecutor Aaron Perkins said after the killing, the pair went on a spending spree with the victim's money and today the High Court at Auckland heard from a tattoo artist who met them on February 2.
Dave Ansted, who worked at Newmarket's Streetwise tattoo parlour, told the court Kumar and Permal were "getting on just fine" when they walked in without an appointment.
"I think they were excited about getting a tattoo . . . there was an element of nervous excitement," he said.
The defendants each opted for "geometric patterns, tribal-type tattoos" on their chest and shoulder area.
Both paid the $350 for their tattoos in cash and he said Permal came back a week later to spend another $400 on having his design extended down his arm.
During cross examination Mr Ansted described Kumar as the leader, while his co-accused was "like 'whatever Shivneel says'".
During his opening, Mr Perkins told the jury Kumar was "the instigator and driving force" behind the alleged crime.
"He considered a sum of money was worth more than Mr Prasad's life," he said.
Muniappa Gounder also served the two men on February 2 while working at Christies Jewellery.
He told the court Kumar bought a sterling silver bracelet and a watch for $590 while Permal splashed out $350 on a silver chain and a watch.
Both paid by eftpos, Mr Gounder said.
The court is expected to hear from other witnesses who served the defendants on the days after the alleged murder.
Police were able to identify the victim only after analysing the fingerprints and pathologists were almost certain the man had been alive when doused in petrol and set alight, Mr Perkins said.
The trial before Justice Geoffrey Venning and a jury of six women and six men is expected to last a month.
