The IRD said Naseeb and Ali were found guilty after a judge-alone trial on jointly committing all 69 tax-related offences for which they were charged.
The IRD said the offending happened between 2010 and 2015.
The tax agency said the overall evasion of income tax and GST amounted to about $750,000, with a further $80,000 unaccounted for PAYE.
Inland Revenue said after some PAYE payments were made, the total loss was about $800,000.
“The judge described it as very deliberate offending in which business income was under-reported for the pair, and also within Supreme when it was later registered, through them filing false returns.”
Naseeb and Ali were each sentenced to three years’ prison.
A PwC liquidators’ report said the company stopped trading in 2015 due to “the director’s poor health and the inability to realise a major debtor”.
In 2016, the IRD claimed $126,819.72 in unpaid GST and payroll tax.
In a final report in December 2020, the PwC liquidators said the director provided only sparse records and the company owed money to Carter Holt Harvey.
It was removed from the Companies Register soon after.
