Best Toaster Oven NZ: Which One to Buy
Toaster ovens promise to replace your main oven for small jobs. Some genuinely do, some just take up bench space. Here's how to tell which is which.
What a toaster oven is actually good at
A toaster oven's real advantage is speed and efficiency for small jobs — reheating a pizza slice, roasting a tray of vegetables for one or two people, toasting more slices at once than a pop-up toaster can manage. It preheats in a couple of minutes instead of the 10-15 minutes a full oven takes, which matters more than people think if you're cooking small portions daily.
Where it falls short is capacity and even heating. Most toaster ovens have hot spots, usually near the heating elements at the back or top, so a tray of biscuits often needs rotating halfway through — something a full-size fan oven handles automatically. If you're regularly cooking for four or more people, a toaster oven becomes a bottleneck rather than a convenience.
Capacity: the number that actually matters
Toaster ovens are usually sold by litre capacity, roughly 9L to 45L. A 9-12L model fits four slices of toast or a small pizza and suits one or two people. Once you get to 20L+ you can fit a small roasting tray or a whole chicken, which starts to genuinely substitute for a full oven for a couple or small family. Below that, don't expect to cook a full roast dinner in one.
Air-fry function: gimmick or genuine upgrade?
Combo air-fry toaster ovens (common at Noel Leeming and Harvey Norman under Ninja, Breville and Russell Hobbs branding) add a stronger fan and higher airflow speed. This is a real, useful upgrade for things like chips, chicken wings and reheating leftovers with a crisp finish, rather than the soggy result you get from a microwave. It's not "as good as a separate air fryer" in most cases because the chamber is larger and less enclosed, so results are slightly less crisp — but for most households it removes the need to own a standalone air fryer at all, which is a genuine bench-space win.
When to skip it entirely
If you already own a good air fryer and a full-size oven, a toaster oven is redundant — you're just buying a worse version of appliances you already have. It earns its keep specifically for small households, dorm/flatting setups, or as a genuinely faster second oven during big cooking days like Christmas.
- 1-2 people, small kitchen: a 12-20L toaster oven with air-fry can replace both your toaster and air fryer.
- Family of 4+: look at 25-45L models or stick with your main oven for anything beyond snacks.
- Even heating: check for a rotisserie or convection fan — plain radiant-element models have worse hot spots.
- Bench space: measure before buying — the larger air-fry combo units are bulkier than they look in product photos.
- Cleaning: removable crumb trays and non-stick interiors save real time; check this isn't skipped on cheaper models.
