The Crimes Amendment Act, 2003, passed into effect in the summer of last year.
Martin Kleintjes, the national manager for the police electronic crime lab, said that man, who was not been named, appeared in the Dunedin district court on Thursday.
The man was accused of gaining unauthorised access to an unnamed company in Maryland, USA.
One of the charges against the man was for interfering with a computer system. Although the act was not in a way that would endanger life, the sentence could lead to up to seven years in prison.
