Vanuatu's Supreme Court has ordered that the Lengkon pay a fine of over $US2,600 and carry out 120 hours of community work for breaching civil aviation rules.
Mr Regenvanu has urged the Public Prosecutor to appeal against the light sentence.
RNZ Pacific correspondent said the public has also criticized the leniency of the ruling on the social media.
