The offences occurred between 2000 and 2007, during which time Woodward also served as CFO at Kidicorp. Woodward was still listed in this position on the organisation's website yesterday.
He was accused of failing to file tax returns or providing incomplete or misleading returns, and failing to provide GST returns. He was found guilty on charges relating to his personal income tax obligations from wages and other payments received from other sources.
Judge Thomas Ingram said he did not believe beyond reasonable doubt that Woodward knew what he was doing wrong when he provided misleading information about his business.
Some of the alleged offences also occurred when TML was no longer operating and this could not lead to a conviction, Judge Ingram said.
The judge stressed the matter was one which involved tax evasion by delay rather than calculated intention. "But the law says that those who deliberately delay assessment of tax are evading the assessment and additional payment and that has been well and truly documented by courts of New Zealand and the law."
Defence counsel David Weaver asked for the interim name suppression to continue so his client could inform family.
Judge Ingram said it was no longer appropriate for name suppression to continue despite the matter likely leading to Woodward's "professional ruin".
"He can ring around now. He's had appropriate time to do that," Judge Ingram said.
Woodward was bailed for sentencing next month.
Outside court, Kidicorp owner Wayne Wright said he was not concerned at the convictions, despite Woodward being employed by Kidicorp around 2005.
"I'm aware of the circumstances and the offences are pretty technical, things like filed late returns, etc. He's worked for me for many years now and he's always impressed me with his honesty and integrity and never done anything to suggest any different," Wright said.
