Summary
- A letterbox drop puts flyers into residential letterboxes in the suburbs and areas you choose, delivered by Oppizi flyer distributors rather than NZ Post
- Plan it in seven steps: goal and offer, areas and targeting, quantity, format, timing, delivery verification, and tracking
- Size a drop from the letterboxes in your areas, minus "No Junk Mail" and "No Circulars" letterboxes, rather than a national total
- Ask every provider for proof of delivery: with Oppizi, every mission is verified by GPS, app check-ins, and geotagged photos, with real-time reporting
- For tracked, GPS-verified Letterbox Drops in New Zealand, Oppizi is the best fit, with 16M+ flyers distributed across the country
Planning a letterbox drop in New Zealand comes down to three decisions: which letterboxes, what goes in them, and how you'll know the flyers landed. Get those right and a drop across a few suburbs in Hamilton or Tauranga can be planned, delivered, and measured with the same discipline as a paid social campaign.
This guide walks NZ marketing teams through each step, from the offer to the tracking, with a planning checklist you can work from. It also covers how to size a drop, how delivery is verified, and who to use. The channel earns its place: a door drop stays in the home for 5.6 days on average, is picked up 3.0 times, and holds 57 seconds of attention, per JICMAIL's Q1 2026 data (UK-measured).
What is a letterbox drop in New Zealand?
A letterbox drop is a flyer delivered by hand into residential letterboxes along planned routes, in the suburbs and areas you choose. With Oppizi, Letterbox Drops are delivered by Oppizi flyer distributors, not by NZ Post, and every mission is verified by GPS and app check-in.
It helps to know how the channel sits next to the other offline options in New Zealand, because the differences change how you plan:
- Letterbox Drops: flyers delivered to residential letterboxes by Oppizi flyer distributors, with suburb, area, and third-party demographic targeting
- Unaddressed Mail: delivered through NZ Post on its regular runs, to residential and business addresses
- Hand-to-Hand Flyering: flyers handed directly to people at high-footfall locations by Oppizi Brand Ambassadors
If you're weighing a letterbox drop against NZ Post delivery, our guide to unaddressed mail in New Zealand covers the other side. Hand-to-Hand Flyering suits a different brief again: people in the moment, rather than households at home.
What are letterbox drops best for?
Letterbox drops are best when the audience is defined by where people live. They work well for:
- Store and location launches: announce an opening to the neighbourhoods most likely to walk in
- Offers with a deadline: put a time-bound promotion in front of households while it can still convert
- Suburb-level awareness: reach every targeted household on a street with the same message, run after run
- Test and scale: prove an offer in one suburb, then extend it anywhere in New Zealand
They're a weaker fit when you need named customers (that is Addressed Mail) or people on the move at a station, event, or shopping precinct (that is Hand-to-Hand Flyering). Many brands run more than one channel and compare results side by side.
How do you plan a letterbox drop in New Zealand?
Seven decisions make up the plan. Work through them in order, because each one shapes the next.
| Step | What to decide | Why it matters |
|---|---|---|
| 1. Goal and offer | One objective and one clear, time-bound offer | The offer drives response and makes the result measurable |
| 2. Areas and targeting | Suburbs, areas, and any third-party demographic filters | Spend lands on the households most likely to act |
| 3. Quantity | Letterboxes in the chosen areas, minus "No Junk Mail" and "No Circulars" letterboxes | Sets your print run and stops you paying for flyers that cannot be delivered |
| 4. Format | A6, DL, or A5, and paper stock | Changes how much you can say and how the flyer sits in the letterbox |
| 5. Timing | The drop window, matched to the offer period | A flyer that arrives after the offer ends is wasted |
| 6. Delivery verification | How you'll see which streets were covered, and when | Without proof of delivery, you cannot tell a weak offer from a missed street |
| 7. Tracking | A QR code, promo code, or dedicated URL on every flyer | Response reports next to your digital channels |
1. What do you want the drop to do?
Start with one objective: awareness for a new location, trial for a new service, or customer acquisition against a target cost. Then give the flyer one offer with an end date. A specific, time-bound offer is easier to act on and easier to measure than a general brand message.
2. Which suburbs and streets should you target?
Choose the suburbs and areas where your customers live, then refine them with third-party demographic data, which Letterbox Drops in New Zealand support. A gym might start with the streets closest to its door, while a childcare centre might weight its selection toward suburbs with more young families. For a deeper look at audience selection, see our guide to targeting demographics with flyers.
3. How many flyers do you need?
Size the drop from the letterboxes in your chosen areas, minus the ones you won't deliver to. The section below on reach explains how. Volume, format, and coverage also drive the budget; our guide to flyer distribution pricing covers what goes into the cost.
4. Which flyer format should you use?
New Zealand uses metric formats, so convert any US specifications before artwork goes to print.
- A6 (148 x 105 mm): compact, suited to a single offer or code
- DL (210 x 100 mm): long and slim, popular for menus, service lists, and vouchers
- A5 (210 x 148 mm): more room for imagery and detail, suited to launches
Whichever you pick, lead with one offer, keep the headline short, mention the suburb or neighbourhood, and make the call to action impossible to miss. Oppizi's Creative Studio has templates sized for flyers if you'd rather not start from a blank page.
5. When should the drop go out?
Match the drop window to the offer period, so every flyer arrives with time left to act. Avoid weeks when letterboxes are already full of seasonal catalogues, and plan larger drops to run over several days so coverage stays even across your areas.
6. How will you know the flyers were delivered?
Ask for proof before you book. With Oppizi, every mission is verified by GPS tracking, app check-ins, and geotagged photo proof, with real-time reporting, so you can see which routes were covered and when. The next section covers delivery in more detail.
7. How will you track the response?
Put a tracking element on every flyer: a QR code, a unique promo code, or a dedicated URL. As a reference point, door drops average a 0.3% response rate, per the JICMAIL Response Rate Tracker (UK-measured). New Zealand has no local response benchmark, so your own tracked results are the number to plan the next drop on.
How many letterboxes can you reach in one drop in New Zealand?
There's no fixed ceiling: one drop can cover a single suburb or run across many areas in several regions. The useful question is how many letterboxes your chosen areas hold, and you answer it in three steps:
- Count the letterboxes in the suburbs and areas you've selected. Ask your provider for this figure with the quote, area by area.
- Subtract the letterboxes you won't deliver to. Letterboxes signed "No Junk Mail" or "No Circulars" are skipped, so they come out of the total.
- Apply your targeting. If you filter by third-party demographic data, the final count covers only the households that match.
That gives you a deliverable quantity for the print run. Many brands start with one or two suburbs to test the offer and creative, then extend coverage anywhere in New Zealand, from Auckland and Wellington to Christchurch and Dunedin, as results come in.
How are letterbox drops delivered and verified?
Oppizi flyer distributors deliver your flyers by hand along planned routes. Every mission is verified by GPS tracking, app check-ins, and geotagged photo proof, and real-time reporting shows the routes being walked as the drop happens, so you're not relying on a completion email as proof.
Delivery also follows the National Code of Practice for the Distribution of Unaddressed Mail, published through the Marketing Association. Letterboxes signed "No Junk Mail", "No Circulars", or similar are skipped. That trims reach slightly, and it keeps your campaign compliant and focused on households open to offers.

Frequently asked questions
- What's the best letterbox distribution service in New Zealand?
For tracked, GPS-verified Letterbox Drops, Oppizi is the best fit: every mission is verified by GPS and app check-in, targeting can use third-party demographic data, and response reports in one dashboard. Local distributors suit small single-area drops and national networks suit broad saturation. Our flyer distributor comparison covers the main providers.
- What's the difference between Letterbox Drops and Unaddressed Mail?
Both reach letterboxes without a mailing list. Unaddressed Mail is delivered through NZ Post on its regular runs, to residential and business addresses. Letterbox Drops are delivered by Oppizi flyer distributors to residential letterboxes, with suburb, area, and third-party demographic targeting, and every mission is verified by GPS and app check-in.
- Do letterbox drops skip "No Junk Mail" letterboxes?
Yes. Under the National Code of Practice for the Distribution of Unaddressed Mail, letterboxes signed "No Junk Mail", "No Circulars", or similar are skipped. Take them out of your count when you size the drop. It trims reach slightly, and it keeps your campaign compliant and your spend on households open to offers.
- How do I know my flyers were actually delivered?
Ask for proof before you book, not after. With Oppizi, every mission is verified by GPS tracking, app check-ins, and geotagged photo proof, with real-time reporting, so you can see which routes were covered and when. Pair that with a QR code, promo code, or dedicated URL on the flyer, and you can see both the delivery and the response it produced.
- When should I choose Hand-to-Hand Flyering instead of a letterbox drop?
Choose Hand-to-Hand Flyering when your audience is defined by where people go rather than where they live: a station, an event, or a busy shopping street. Brand Ambassadors hand the flyer over in person. Choose a letterbox drop when you want household coverage across specific suburbs and areas.
