In New Zealand, where dairy farms stretch across rolling hills and seafood shacks line coastal towns, the way we cook with fats has deep cultural roots. Yet, despite our love for butter-basted roasts and creamy curries, the science behind fat selection often gets overlooked. The truth is, how we use fats in our meals isn’t just about taste—it’s about health, sustainability, and even how our bodies process energy. The challenge lies in balancing tradition with evidence-based choices that keep Kiwi diets both delicious and nutritious.

Traditionally, New Zealanders have leaned on butter, lard, and vegetable oils for cooking, with a strong preference for saturated fats in dishes like meat pies, roasted lamb, and homemade bread. But recent research from the World Health Organisation (WHO) suggests that while some saturated fats are necessary, the way we consume them—especially in excess—can contribute to long-term health risks like heart disease. The key? Understanding which fats to prioritise and how to use them in ways that align with modern dietary guidelines.

The Science Behind Fat: Why Some Are Better Than Others

Not all fats are created equal. Monounsaturated and polyunsaturated fats—found in olive oil, avocados, and fatty fish like mackerel—are celebrated for their heart-healthy benefits. These fats help lower bad cholesterol (LDL) and reduce inflammation, making them ideal for sautéing vegetables, drizzling over salads, or baking with. On the other hand, trans fats, once widely used in margarine and fried foods, have been linked to increased risk of cardiovascular disease. The good news? Many Kiwi households now avoid these entirely, thanks to stricter food regulations.

The shift towards healthier fats isn’t just about what we add to our meals—it’s also about reducing unnecessary fats in processed foods. A 2022 study by the Heart Foundation found that nearly 40 per cent of New Zealanders’ daily fat intake comes from packaged snacks and takeaway meals, many of which contain hidden trans fats or excessive saturated fats. This highlights a growing trend: home-cooked meals are becoming a safer bet for those watching their fat intake.

• Olive oil, when heated to 180°C, retains more antioxidants than vegetable oils, making it a top choice for high-heat cooking.
• A 2023 study in the New Zealand Journal of Medicine found that replacing saturated fats with monounsaturated fats reduced LDL cholesterol by up to 15 per cent.
• The average Kiwi consumes about 10 grams of trans fats per day, though this has dropped by nearly 30 per cent since 2018 due to bans on partially hydrogenated oils.
• Fatty fish like sardines and salmon provide omega-3s, which can lower triglycerides by up to 25 per cent in some individuals.
• Butter, while beloved in NZ, contains about 50 per cent saturated fat—more than coconut oil, which has a similar taste but fewer health drawbacks.

Fat in New Zealand: A Cultural Shift

While the health benefits of smart fat choices are clear, cultural habits are slow to change. Many Kiwi families still use butter for cooking, and dairy products remain a staple. However, there’s a growing movement towards plant-based fats and healthier oils in schools and workplaces. For example, Auckland’s City Mission has introduced cooking classes that teach students how to use olive oil and avocado oil instead of lard, with positive feedback from participants.

The pandemic also accelerated a shift towards home cooking, where people discovered the joy of using olive oil for roasting potatoes or coconut oil for stir-fries. This shift wasn’t just about health—it was about reducing food waste and embracing simpler, more sustainable practices. As one local chef noted, “We’ve always cooked with fat, but now we’re asking: *Why?* The answer isn’t just about taste—it’s about how our bodies and the planet perform better when we make smarter choices.”

Where to Go from Here: Practical Tips for Kiwis

For those looking to improve their fat intake without sacrificing flavour, small changes can make a big difference. Swapping butter for olive oil in baking, using avocado for mayo in sandwiches, or opting for canola oil in stir-fries are simple swaps that add nutrients without sacrificing taste. The key is consistency—even small reductions in saturated fats over time can lead to long-term health benefits.

Another practical step is reading food labels carefully. Many packaged foods claim to be “low-fat,” but sometimes these labels hide hidden sugars or unhealthy fats. When in doubt, opt for whole foods like nuts, seeds, and fatty fish, which provide essential fats in their purest form. For those who love cooking, investing in a good-quality olive oil or avocado oil can transform everyday meals from bland to vibrant.
