Air Fryer vs Multi-Cooker: Which Kitchen Appliance Do You Actually Need?

Standing in front of the appliance aisle (or scrolling a benchtop appliance page) with two very different boxes in mind is a familiar problem for New Zealand cooks. An air fryer promises crispy chips and reheated leftovers in minutes. A multi-cooker promises a fall-apart lamb shoulder after eight hours of doing nothing. Both are useful. Neither is a replacement for the other, and that's the part most buying guides skip over.

This guide breaks down what each appliance is genuinely good at, where they overlap, and how to decide which one (or both) belongs on your bench.

What an Air Fryer Actually Does

An air fryer is a small convection oven with a powerful fan mounted above a basket or drawer. Hot air is forced rapidly around the food, crisping the surface the way deep frying does, but using a fraction of the oil and far less time than a conventional oven. That's the whole trick: speed, crisp texture, and minimal cleanup.

Air fryers are strongest at:

• Chips, wedges, and roast vegetables with a genuinely crisp finish
• Reheating takeaways, pizza, and fried food without the sogginess a microwave leaves behind
• Frozen snacks (nuggets, spring rolls, fish fingers) cooked straight from the freezer
• Small batches of protein such as chicken thighs, salmon fillets, or bacon

Where they fall short is capacity and liquid-based cooking. Most baskets can't handle a full roast dinner for a family of five in one go, and an air fryer will not simmer a curry, cook rice, or slow-braise anything. It's a dry-heat, high-speed tool.

If your household mostly wants quicker, crispier versions of oven food, an air fryer from the Tech Supply Shed Air Fryers range is usually the appliance to start with.

What a Multi-Cooker Actually Does

A multi-cooker (sometimes sold as a pressure cooker or by the Instant Pot name specifically) is built around a sealed inner pot that can pressure cook, slow cook, steam, sauté, and often make rice, yoghurt, or stock, all from one appliance. Where an air fryer is about speed and crisping, a multi-cooker is about depth of flavour and hands-off cooking.

Multi-cookers are strongest at:

• Slow-cooked meals like casseroles, curries, and braised meats that need hours to break down
• Pressure-cooked dishes (dried beans, tough cuts of meat, bone broth) finished in a fraction of the usual time
• Rice, risotto, and grains cooked evenly without babysitting the stove
• Batch cooking larger volumes of soups and stews for the week ahead

The trade-off is texture. A traditional multi-cooker without a dedicated air-fry function will not give you the same crisp finish as a standalone air fryer; most models are built around sealed, moisture-retaining cooking rather than open, dry heat. Some newer multi-cookers now include an air-fryer lid or air-fry mode as an add-on, which narrows this gap, so it's worth checking the individual model's functions if crisping matters to you.

For households that lean on slow-cooked meals, batch cooking, or big pots of rice and grains, a multi-cooker from the Tech Supply Shed Multicookers, Slow Cookers & Rice Cookers range will get more weekly use than an air fryer will.

Air Fryer vs Multi-Cooker: Side-by-Side Comparison

Which One Should You Buy?

The honest answer depends on how you actually cook, not on which appliance is trending. A few quick scenarios:

• You cook mostly quick weeknight meals for one or two people: an air fryer, such as the Philips 2000 Series 6.2L Air Fryer XL, covers most of what you need with minimal cleanup.
• You batch cook, meal prep, or feed a larger family regularly: a multi-cooker such as the Instant Pot Pro 8L Multicooker earns its bench space with hands-off, high-volume cooking.
• You want crispy sides and reheated leftovers without turning on the oven: lean air fryer. Look at larger dual-zone models like the Ninja AF500 XXXL FlexDrawer Air Fryer if you're cooking for a family.
• You want fewer pots, one-pot curries, and rice on autopilot: lean multi-cooker. A compact option like the Instant Pot Rio Wide 7.1L Multicooker suits smaller kitchens.

Do You Actually Need Both?

If your budget and bench space allow it, the two appliances are genuinely complementary rather than duplicated. A common pattern in NZ kitchens is a multi-cooker doing the slow, hands-off cooking during the day (a curry, a stock, a batch of pulled pork) while the air fryer handles the sides and the reheating in the evening, chips, roast vegetables, or crisping up that pulled pork for tacos. Neither one makes the other redundant; they cover opposite ends of how food gets cooked.

If you can only fit one appliance on the bench right now, base the decision on your last two weeks of actual cooking rather than what looks impressive in a photo. Cooked more rice, curry, or soup than usual? Multi-cooker. Reached for the oven mostly for chips, reheats, or a quick protein? Air fryer.

Frequently Asked Questions

Can an air fryer replace a multi-cooker?

No. An air fryer uses dry, rapid hot air and is built for crisping and quick cooking, not for pressure cooking, slow cooking, or simmering liquids. It can't replicate a braise or a pot of rice the way a multi-cooker can.

Can a multi-cooker make food crispy like an air fryer?

A standard multi-cooker cannot replicate an air fryer's all-over convection crisping. However, some newer multi-cookers include a dedicated air-fryer lid or air-fry mode, so check the individual model's functions if crisping matters to you.

Which is better for a small kitchen in New Zealand?

If bench space is tight, an air fryer generally has a smaller footprint for its capacity than an equivalent multi-cooker, making it the easier fit for compact NZ kitchens and apartments.

Which appliance uses less power?

Air fryers typically run for shorter cycles (10-25 minutes) at higher wattage, while multi-cookers on a slow-cook setting run for hours at lower wattage. Total energy use ends up broadly similar depending on the recipe and setting used.

Is it worth buying a dual-zone or dual-basket air fryer?

If you regularly cook two different foods at once (say, chips and chicken with different cook times), a dual-zone model like the Ninja AF500 or Ninja DoubleStack range avoids overcrowding a single basket and keeps both foods properly crisp.

The Bottom Line

An air fryer and a multi-cooker solve different problems: one is about speed and crisp texture, the other is about depth of flavour and hands-off, high-volume cooking. If you're mostly after quicker, crispier versions of oven food, start with an air fryer. If your cooking leans toward curries, batch meals, and rice, a multi-cooker will see more use.
