A Tauranga man has been sentenced to two years in prison for possessing child sexual exploitation and abuse material.

David Frederick Moore, 56, pleaded guilty to four charges of making a copy of an objectionable publication for distribution and one representative charge of possessing objectionable publications when he appeared in the Tauranga District Court on Wednesday.

Moore was previously convicted in 2008 of possessing objectionable images.

Following a tip off from the United States' National Centre for Missing and Exploited Children, Internal Affairs inspectors raided Moore's home and discovered almost 4000 objectionable pictures or videos on computer equipment which they seized.

Censorship compliance manager Stephen Waugh says the department continues to work closely with international agencies to detect people using the internet to traffic in child sexual exploitation and abuse material.

'We continue to meet the challenges presented to us by people who attempt to conceal their offending from us and our international partners.

'We work towards ensuring our community is safe from this material and its effects, material that always represents abuse to a child victim. This is not a victimless crime.”

Moore was one of two men jailed this week for possessing child sexual exploitation and abuse material.

Appearing in the Napier District Court on Thursday, podiatrist Neville Bruce Crockett, 62, was sentenced to four-and-a-half years' jail after pleading guilty to two representative charges of possessing objectionable publications, seven of making a copy for distribution and one charge of obstruction.

Internal Affairs seized computer equipment containing more than 5000 files of child sex abuse, from Crockett's home after US authorities told the department he had tried to email pictures of young children being sexually abused.

Crockett tried to conceal a USB drive from an inspector during the search and had used many computer applications to conceal his activity. He had also visited on the ‘dark web' two child sexual abuse websites subsequently closed down by the FBI.

Napier District Court Judge Geoff Rea said Parliament had sent a message that there was zero tolerance for this offending when, in May 2015, it doubled the maximum penalty for possessing objectionable publications to 10 years' imprisonment.

Both men's offending was subject to the stiffer penalties, added Judge Rea.
