“What we’re finding is because of wet there’s been a lot more disease in the trees pre-harvest, so smaller growers just haven’t bothered harvesting this year,” Glover said.
“The cost just wasn’t worth it for them when they had low volume of product - so I guess that’s where it’s fallen out.
“It is really disappointing, but it’s been tough,” she said.
Unfortunately, fungal fruit disease anthracnose has affected around a third of local olive production, she said.
It was seen as the worst disease for olive fruit globally, spreading easily in warm and wet weather - and rotting the fruit from the inside out.
“Anthracnose is one of the bigger problems. A lot of groves across the country, especially in the North Island, that have never seen it in the grove before, have got it quite badly and that affects the fruit. Fruit that’s got anthracnose in it, it ruins the oil, so you can’t produce it.
“Oil that I’ve received to go get certified to be extra virgin olive oil is down on numbers probably about a third compared to last year at this stage, but I’m hoping there will be some late oil coming through.”
Global prices for olive oil continue to rise after heat and drought hit the Mediterranean earlier this year, especially in Spain which has resulted in a smaller supply.
Glover said she expected consumer prices for olive oil to continue to rise while Europe holds low volumes of oil and Australian growers also reported a difficult season with lower yields.
