On 1 May 2025, NZFiMA said Kok Ding Cheng has been ordered to pay a pecuniary penalty of NZD 198k for market manipulation pertaining to substantial shareholding.

• The Court found Mr Cheng deliberately placed trades worth NZD 59 - 540 to inflate RUA share prices, breaching section 265 of the Financial markets conduct act 2013.
• The orders lacked a genuine commercial purpose but for increasing the price and/or demand for RUA shares when Cheng held a substantial shareholding in the company.
