The world's most expensive honey from New Zealand has just got even pricier.

The True Honey Company has produced a higher grade, even scarcer variety of UMF33 rated mānuka honey and has 200 jars of the liquid gold up for grabs.

London's luxury department store Harrods has snapped up all 200 jars produced, and the honey is so rare not even True Honey is selling it on its website.

For £2595 - around $4964 New Zealand dollars - per 230g jar, the honey weighs in at close to an eye-watering $20,000 per kilogram.

Jim McMillan, founder of the True Honey Company, joined Mike Hosking to explain why people are so desperate to get hold of his honey!
