Depression triggered by his teenage son's death in the Christchurch earthquake was behind a man's descent into the world of child pornography, a court has heard.
John Andrew Howland, 38, moved to the West Coast soon after the earthquake and now lives in Greymouth, where a police raid on September 25 revealed he had thousands of images of children, some just toddlers, engaged in sexual acts with adults, stored on his computer.
For the purposes of prosecution, police selected a sample of seven images as a basis for the charges, which Howland admitted in the first instance.
"Unguarded'' comments from Howland to an acquaintance had concerned that person enough to contact police.
In Greymouth District Court yesterday, lawyer Richard Bodle said Howland's curiosity developed into an obsession, but he had not produced or distributed any images.
