Professor Peter Lineham has been writing and teaching about New Zealand's religious history for several decades.
He's retiring from Massey University at the end of this year, but not before he gives one final lecture about the state of religion in the country - its decline, evolution, and future here.
The lecture titled In Search of church - does religion have a future in Godzone? is the tenth and last in this year's Our Changing World Series and will be delivered tonight.
Professor Lineham joins us now to tell us about the topic, and leaving teaching behind.
