I've been yapping about this all day.

From stuff.co.nz:

The lead sentence imposed in Operation Pukapuka – the Maori word for book – was five and a half years on Lee Simpson, 44, for what the sentencing judge called 10 years of systematic thefts. It was reduced to three years on appeal.

The investigation wraps up in November with the sentencing of Simpson's brother Tyler Scott Simpson, 44, who admitted a single charge of receiving.

Operation Pukapuka cracked down on the organised theft of at least 2500 books over 10 years, with a retail value of at least $1 million.
