“I became a vegan in my late 30s, this time on more ethical grounds.
“I’m not anti‑farming at all – the world has to be fed, and unless the movement for plant‑based food really takes off, people will continue to eat animal products.
“It’s a personal decision for me not to eat factory‑farmed food or byproducts.”
While Oliver has always been interested in growing organically, the veganic aspect followed later.
“Veganic gardening means you don’t use any inputs from farmed or fished animals – so no fish‑based products, no blood and bone, no sheep pellets, no animal manure, and an important one for me, no chicken litter from factory‑farmed poultry.”
Bridson is a big supporter of Oliver’s veganic gardening and has helped with the infrastructure for the garden, including an additional water tank, water lines to the gardens, a polytunnel, and a processing shed.
From 2015, Oliverh began seriously experimenting with veganic techniques, and the land was fully certified organic in 2019.
This year, she has taken the plunge and up-scaled to a market garden.
A learning curve
“I’ve found that being vegan and growing food veganically and organically means I’m constantly learning,” she said.
“It takes a lot of time, experimenting, and gaining knowledge.”
In her own diet, Oliver finds good plant‑based protein sources in nuts, lentils, soybeans, corn, chickpeas, linseeds, and beans of all kinds.
“She has had some success growing the latter three in the Waikato climate.
“The market garden covers around 400 square metres, which is potentially enough for market requirements, but I would like to increase the size.”

She uses a “chop and drop” approach with cover crops, including clover, lupins, and phacelia, to build fertility.
Keeping the soil well mulched with grass clippings from around the property makes a huge difference, along with crop rotation.
She is also exploring polycropping, influenced by another grower who is having great success with the technique.
Two seasons ago, non‑invasive willow trees were planted along a small wetland area on the property.
Oliver has started coppicing them and using the branches for ramial woodchip mulch.
“The method is to cut branches less than seven centimetres in diameter from deciduous trees in winter, chip them, and lay them around fruit trees.
“A small amount is also used in the green‑manure phase of the rotation cover crop plan.
“Compared to larger trunk wood, this material is rich in nutrients and minerals and has a lower carbon‑to‑nitrogen ratio.”
Oliver is slowly building up her own compost and sometimes buys compost made from plant material. She also uses seaweed fertiliser products.
Friends and foes
“I’m passionate about encouraging native species, whether it be worms, bees, birds or other fauna.”
The key to this is diversity.
Native bush has been planted throughout the property, along with fruit trees such as plums, apples, and figs, providing a large variety of food sources that attract beneficial creatures.

“There are so many birds in the garden, and they take care of the snails for me,” she said.
“This year, we were inundated with slugs, and I collected them for several weeks and relocated them to another area of the property – that worked well to rebalance the population.”
The cabbage white butterfly was kept at bay using butterfly netting, and Olier said the difference was significant.
Mulching encourages worms, other soil life, and moisture retention.
There are about 180 known native species of worms in New Zealand, as well as introduced species.
Native planting brings beneficial insects and native bees to the garden.
Some bees nest in the ground, others in wood, and the family ensures they have space to go about their business.
Oliver would love to expand her veganic market garden.
She spends time visiting other growers, watching YouTube videos, and reading widely on the topic.
