Wanaka beekeeper Daniel Schweizer is investigating a use for drones that is yet to catch on in New Zealand.
He can see potential for "spray drones" that target weeds in difficult-to-get-to places in the high country.
The weeds would include gorse, broom and wilding pines.
"The only options at the moment are a helicopter and a man with a knapsack, and one is $20 an hour and one is $2000 an hour," he said.
