Masters Of Oil
WORDS Annie Studholme

Behind New Zealand’s only locally-produced cold-pressed extra virgin rapeseed oil and high oleic sunflower oil is a Canterbury business with lofty aspirations to raise the quality of everyday culinary oils used by discerning foodies nationwide.


During late spring and early summer, crop fields in the South Island come to life with the golden flowers of premium rapeseed. Once destined for the biofuel industry, the tiny black seeds are now turned into high-quality food grade oil by Rolleston-based company Pure Oil New Zealand, under its brand The Good Oil.


In four short years, The Good Oil has emerged as one of the major players in the New Zealand culinary oil market with its extra virgin cold-pressed rapeseed oil finding favour with foodies nationwide. On the back of the success of its first offering, The Good Oil has recently introduced New Zealand’s first home-grown cold-pressed high oleic sunflower oil and is also exploring human food uses for plant proteins from rapeseed meal.


‘It’s an exciting time for us,’ says Pure Oil NZ Managing Director Nick Murney. ‘We are now the tenth biggest oil brand in New Zealand. To get a retail brand to the size we have is a big achievement, and we think we can double that.’ But it’s taken a great deal of time, effort and perseverance.


A former investment banker, Nick previously worked as agribusiness manager for Solid Energy. When the state-owned coal miner decided to cut its losses, selling off its bio-fuel businesses including the purpose-built canola (rapeseed) pressing plant at Rolleston, Nick jumped at the opportunity. ‘It was a big, beautiful asset that was going to be scrapped. The opportunity came up and I grabbed it. I could see real value in what we were doing,’ he says. ‘If I had known the amount of stress it would cause me I might not have gone there. I was probably a little bit brave, and a lot stupid.’


It wasn’t long before he had other investors on-board including Southern Packers, a group of Mid and South Canterbury small- to medium-scale onion and potato growers, consultant agronomist Roger Lasham, and Ashburton-based seed company Midlands. ‘It came together quite quickly. People could see the potential.’


Right from the outset, their focus was on producing quality food grade oil, not on biofuel. Using the same cold-pressing techniques employed by olive growers to preserve the olive oil’s natural colour, unique flavour and nutritional benefits, Pure Oil NZ went against the grain. ‘Initially, people thought that cold-pressed rapeseed oil wasn’t fit for human consumption, but there was already a big market in Britain and Europe.’ Imported rapeseed oil, also known as canola, is commonplace on our supermarket shelves as a cheap salad and cooking oil, with millions of tonnes of seed grown worldwide. 



But Nick’s quick to point out that not all oils are created equal. The imported varieties are extracted from seed using added heat (seed heating) and chemicals (solvent extraction). After solvent extraction, the crude oil is refined, bleached and deodorised (RBD) to produce an odourless oil which is opaque in appearance. The RBD process does not rely on high-quality seed oil as the intensive processing removes any unwanted components from the crude oil, he explains.

Whereas Pure Oil NZ cold presses locally-produced rapeseed using no added heat or chemicals, delivering an extra virgin rapeseed oil which has a mild, nutty taste, delicate aroma and is richly golden in appearance. ‘You get less oil, but you get a higher quality product that retains its unique characteristics.’ 


It also helps to maintain the oil’s health-giving properties. The Good Oil is a naturally rich source of Vitamin E, an essential fat-soluble vitamin and antioxidant that helps protect the body’s cells from oxidative damage, and is 50 per cent lower than olive oil in saturated fats and contains no trans fat. As it’s high in mono-unsaturated (the good ones) fats, it’s one of the only unblended oils that can be heated to high frying temperature and not spoil its antioxidants, character, colour or flavour.   


Pure Oil NZ sources GE-free seed for planting. It has more than 60 farmer growers that supply High Oleic Low Linolenic (HOLL) rapeseed for crushing, mainly from throughout South Canterbury and Southland. For farmers it’s a good dryland crop which fits well into crop rotations. It is traditionally planted in March, and harvested the following January, with Pure Oil NZ supporting farmers every step of the way.


Nick says cold pressing extra virgin rapeseed oils relies heavily on the innate quality of the oil contained in the seed. That quality starts with the farmer’s fields, right through to agronomy advice and climatic conditions. Once it gets to the crushing plant, best practices for seed handling, drying and storage help maintain the seed quality. ‘You get one shot at cold pressing. Do it right, you get a lot of quality oil; do it wrong and you’ll be selling it for stock feed.’


Pure Oil NZ started with just two products – standard oil and a high-protein meal by-product of the extraction process. Over time, they have developed a range of products to sit alongside their commercial kitchen oils including equine products Leg Up Performance Oil and Pure Gold, and industrial oils Ezi Cover Adjuvant Oil and Not So Dusty Dust Suppressant. They also imported equipment from the United States which was adapted to produce a specialised high-energy, high-protein meal for the dairy industry, aimed at intensive dairying, particularly indoor operations. 


Branching into the retail market was always on the cards, but admittedly it took time to come to fruition, says Nick. ‘It starts with an idea, but there’s a lot to do from designing a label to sourcing the right bottles. It took a lot of work by a lot of people to get it on the shelves. There was nothing else like it. It was a completely new product. We thought long and hard about the brand and all that goes into it. Having a great product is only part of it; you have to have the right packaging.’


After four years in the pipeline The Good Oil was finally launched in South Island New World stores in 2016 to a receptive market. As word gets out, sales have steadily continued to increase. It can now be found on supermarket shelves nationwide with Countdown recently joining New World and Fresh Choice, as well as numerous speciality stores.


With its high smoke point, mild flavour and on-point pricing, people have started to cotton on that The Good Oil is perfect for everyday use in the kitchen. It can be used in everything from baking and frying, but it’s equally delicious in salad dressings. ‘We have deliberately tried to keep The Good Oil reasonably priced, so it can be an everyday oil, rather than pricing it as a speciality oil,’ says Nick.


Encouraged by the success of its extra virgin cold-pressed rapeseed oil and driven by customer demand, Pure Oil NZ has just released New Zealand’s first home-grown naturally cold-pressed high oleic sunflower oil to the market. 


Pure Oil NZ started experimenting with specially-bred sunflowers in Canterbury in 2017 with an area of 65 ha. That area increased to 300 ha for this season which would produce about 400 tonnes of oil, and that’s just the start point, says Nick.


Initially, its focus has been on meeting local demand while they come to grips with growing and processing the new crop, but the future looks promising. Tens of thousands of tonnes of sunflower oil was imported annually for use in infant formula, snack foods, baking and other foods. But, he warns, it will take time to develop it as a primary crop for arable farmers. 


The biggest challenges to growing sunflowers are limited access to imported hybrids, and bird damage. Sunflowers have to be harvested at high moisture and dried in a bid to outrun the birds. The processing also requires a different technique from rapeseed. But the final product is worth it, explains Nick. 



While overseas-produced sunflower oils are heavily processed and lose their flavour, The Good Oil’s extra virgin cold-pressed method ensures it retains its mild, nutty taste. It is also a healthier option than standard sunflower oil. To date the response has been favourable, with loyal Good Oil customers already raving about the new product.

Too Good to be True?

By Nathan Miglani • May 22, 2024
We are on the cusp of a once-in-a-decade influx of properties on the market. Nathan Miglani, Director of NZ Mortgages, explains. As we have discussed, in the aftermath of the election we saw immediate momentum in the market. Since March we have seen this start to drop as the reality of interest rates remaining high dampened buyers’ appetite. Petrol prices are high, the cost of living continues to increase and while the OCR is holding, and forecasted to hold for the next few months, people are hurting, which in turn sees the property market slow. But there is hope on the horizon – we are predicting that by September/October we will start to see interest rates slowly start to come down, but do not expect them to drop as quickly as they rose. We are seeing some banks offer as low as 5.99 per cent on a three-year loan, and while this might sound good now, my advice is still to only fix for a short term to avoid costly break fees. The most active market we are seeing right now is in the $800,000 – $1.3 million range with lots of buying and selling happening. This is set to ramp up come 1 July with the changes to the bright-line property rule when it comes to being taxed on capital gain – dropping from 10 years (or five years for a new build) to two. For many it will seem too good to be true, but it is! This is set to put in motion a once-in-a-decade influx of properties to the market from Mum-and-Dad investors who are currently hurting with the high interest rates, creating massive opportunity for both first home buyers and first-time investors. Other sectors of the market continue to feel the pinch and as an advocate and passionate developer it was important to me to be able to assist the construction sector, which sees the launch of our construction division, Construction Loans. This is for those who have decided to build their first home, right up to those developing a subdivision. It is about helping everyone achieve their goals – which underpins everything we do. For this sector, it is about ensuring that the finances are in order before it is too late. Arranging finance for building a property is different from securing finance on an existing home, and it is critical to consider the best way to structure repayments on the section and the build while maintaining lifestyle.  It is about empowering builders, developers and everyone to make informed decisions that work for their unique situations. There is no one size fits all, which is why it is imperative that you seek professional advice before it’s too late. We are here to help you avoid pitfalls.

The Future of Happiness

By Dr Cheryl Doig • May 22, 2024
Dr Cheryl Doig explores why a holistic approach, when it comes to educating, parenting and governing should be considered. It’s a complex world that our young people are growing up in. Societal change, the impact of social media and technology are colliding with climate change, misinformation, disinformation, and warfare. Trust in governments has deteriorated and the world is more polarised. It’s no wonder wellbeing and happiness are such a focus in our schools, our homes and our businesses. The recent results from the 2024 Global Happiness Index showed that happiness in Aotearoa New Zealand has fallen significantly for all age groups, but by twice as much for the young as for the old. In 2021–2023, our young people were the least happy age group. Females under 30 have one-third more negative emotions than males. Our young people are not thriving. Contrast this with 2006–2010 results, when the young were happier than those in the midlife groups, and about as happy as those aged 60 and over. The Anxious Generation: How the Great Rewiring of Childhood is Causing an Epidemic of Mental Illness by Jonathan Haidt provides some insight into what might be happening here. Haidt refers to our young people as ‘the anxious generation’ and outlines the following as contributing factors: Technology – constant connectedness and the facade of always appearing happy and successful on social media. The cult of safety – overprotective parents and risk aversion – not developing resilience nor the ability to cope with challenges. The loss of play – the decline of unstructured play and outdoor exploration, critical factors for social, emotional and cognitive development. The pressure to succeed – intense academic and extracurricular expectations. The loneliness epidemic – social isolation is more prevalent even though our children appear more ‘connected’. These are deep social issues that have no simple solution. What is needed is an holistic approach to parenting, educating and governing. A focus on literacy, numeracy and sciences alone is not going to lead to a wellbeing economy. Supportive relationships and acceptance of diversity matter more than ever. Creative and critical thinking, play and physical exercise cannot be forgotten. Futures thinking is one way of developing resilience, risk taking and autonomy, as it explores alternative world views and encourages anticipating a range of scenarios. Many of our teachers know this but struggle with the ever-changing pendulum swings of successive governments. They’re exhausted and not so happy in their work. Schools need that sense of community support. We are overdue for a bipartisan collective vision for education in order to create a future where our young people thrive, are hopeful and happy. It’s not all doom and gloom. We can make a positive difference! As parents, whānau and communities, my challenge to you is to consider one item from the bullet point list above. Lean into it and give your children a bit of space to be children and have joy in their lives. Don’t crowd them, cosset them and control them so much. Walk alongside and guide them. Let them learn from failure with you as their coach. Celebrate successes.
