A lot of the schools I visit still have projectors. Some of them are running perfectly fine, bright, reliable, doing exactly what they need to do. Good quality laser projectors in particular are a genuinely capable solution: very bright, extremely reliable, and now available with wireless connectivity via Miracast and AirPlay. Some models even include interactivity. Others are running on borrowed time: dim lamp bulbs, overheating, teachers working around them rather than with them.
The question of whether to upgrade isn't just about the hardware. It's about what your kaiako actually need to teach well, what your budget can realistically support, and whether an interactive panel will genuinely change how your classrooms work, or just be expensive furniture. A quality laser projector is also a legitimate long-term choice for the right room.
Here's how I think about it.
What's actually different about an interactive panel?
A projector displays content. An interactive panel displays it, responds to it, and lets teachers and students interact with it directly, annotating, moving things around, pulling up resources, casting from devices, and running purpose-built classroom software.
The practical differences that matter most in a classroom:
| Factor | Lamp projector | Laser projector | Interactive flat panel |
|---|---|---|---|
| Visibility in daylight | Often poor, curtains required | Very good — brightness comparable to a panel | Bright display, no curtains needed |
| Touch and annotation | Limited or none | Available on interactive models | Built in, highly accurate |
| Ongoing maintenance | Bulb replacements ($200-$400 each) | No consumables, minimal maintenance | No consumables, LED backlit |
| Setup time | Warm-up required, calibration | Instant on/off, no warm-up | On in seconds, no calibration |
| Audio | External speakers needed | External speakers needed | Built-in speakers, often excellent |
| Device casting | Via HDMI or adapter only | Wireless via Miracast and AirPlay | Wireless casting built in |
| Software ecosystem | None | Limited — some models include apps | Full classroom software platform |
| Lifespan | 5-7 years (bulb dependent) | 15-20 years (laser light source) | 10-15 years (LED panel) |
| Upfront cost | Lower | Higher — often comparable to or above a panel | Higher |
The interactive panel wins on software and audio. But a quality laser projector is a genuinely capable, long-life solution that now matches a panel on brightness and wireless connectivity. The main trade-off is cost: good laser projectors are expensive, sometimes more so than an equivalent panel. The right choice depends on the room, the budget, and how your teachers want to teach.
Signs it's time to upgrade
These are the situations where I'd tell a school to move. Not because the projector is old, but because it's actively getting in the way of teaching.
Your teachers are working around the technology
Closing blinds before every lesson. Waiting for the projector to warm up. Avoiding activities that need interaction because it's too clunky. When the tool creates friction rather than reducing it, it's time.
The bulb is due for replacement again
Projector bulbs cost $200 to $400 each and last around 3,000-5,000 hours of use. If you're replacing bulbs every couple of years, the cost of keeping the projector running starts to look different. Factor in a new bulb plus the labour to fit it, and the gap between projector and panel narrows faster than people expect.
Visibility is a genuine problem
If your classrooms get a lot of natural light and the projected image is dim or washed out, your teachers are fighting a losing battle. Panels are bright enough to use in full daylight. This single factor alone significantly changes the quality of lessons that involve the display.
You're planning a classroom refresh anyway
If you're repainting, recarpeting, or refurnishing, it's a natural point to reconsider the technology too. Installing a panel when walls are already being touched is cheaper and less disruptive than doing it standalone.
Your staff want to teach differently
Collaborative learning, live annotation, student device casting, interactive lessons, these are genuinely easier with a panel. If your kaiako are frustrated by what they can't do, the technology is limiting their teaching.
Signs you can wait
Not every school is ready to upgrade, and not every projector needs replacing. Here's when I'd say hold off.
Your projector is less than three years old and working well
If the bulb is bright, the image is clear, and teachers aren't complaining, don't replace it yet. Stage the investment across your rooms and start with the ones that would benefit most.
Your rooms have controlled lighting and the display is visible
Some classrooms are genuinely well-suited to projection, darker rooms with good blinds and a quality projector can work well for years. If visibility isn't a problem, it's not a reason to upgrade.
The budget isn't there yet
An interactive panel done right, supply, installation, and proper training, is a meaningful investment. If the budget would mean cutting corners on installation or skipping training, wait until you can do it properly. A poorly installed or underused panel is a worse outcome than a working projector.
"The worst outcome isn't keeping the projector. It's spending $8,000 on a panel that sits in a room collecting dust because nobody knows how to use it."
What does the upgrade actually cost?
Below is an indication of costs when considering upgrading your classroom to an interactive panel.
| Item | Typical NZ cost range | Notes |
|---|---|---|
| Interactive panel (65") | $3,500 - $5,500 | Varies by brand and tier |
| Interactive panel (75") | $4,500 - $8,000 | Varies by brand and tier |
| Interactive panel (86") | $5,500 - $9,000 | Premium brands at top of range |
| Wall mount and installation | $800 - $1,500 | Includes cable management |
| Electrical work (if needed) | $300 - $800 | Depends on room setup |
| Teacher training (half day) | $500 - $800 | Per session (covers a group) |
| Total per room (typical) | $7,000 - $13,000 | Supply, install, and training |
For context: an Ultra Short Throw projector starts from around $3,000 for a lamp model and $4,500 for a laser, before installation. Installation costs for a UST projector are typically higher than for an interactive panel. You also need to factor in speakers and an HDMI input point, which add to the total cost of the solution. A ceiling-mount projector is a cheaper alternative, but limits you to display-only use and introduces the shadow effect when the teacher or students stand near the screen. Over a 10-year period, the total cost of ownership is closer than the upfront numbers suggest.

Is it worth it?
The honest answer: it depends on how well you support the transition.
Schools that invest in training alongside the hardware see real changes in how teachers teach. They use the panels daily. Lessons are more engaging. Teachers report feeling more confident with technology. That's a real return.
Schools that buy panels without investing in training tend to see them used as expensive display screens, HDMI in, slide deck up, same as the projector. That's not a return on anything.
The technology doesn't transform teaching. The training does. The technology enables it.
How to make the call
If you're genuinely unsure whether to upgrade, this is a good framework:
- Start with your worst rooms. Which classrooms have the most visibility problems, the dimmest images, the most teacher frustration? Start there, not with a blanket rollout.
- Do a staged rollout. One or two rooms first. Train the teachers properly. See how they use it. Then expand from there based on what you learn.
- Budget for training, not just hardware. If the training budget isn't there, wait until it is.
- Get independent advice before you buy. Your AV supplier should be telling you which rooms need panels and which don't, not pushing you to replace everything at once.
David's take
I've been in classrooms across Auckland, Northland, and Waikato where the projector is genuinely the right tool for that school at this point in time. And I've been in classrooms where keeping the projector is holding kaiako back every single day. The difference isn't the technology, it's the situation. If you're not sure which one you're in, I'm happy to have an honest conversation about it. No obligation.
