Description

The Uniden R3nz is one of the most reliable radar detectors we’ve sold — a long-range GPS detector that quickly built a strong reputation when it launched and has held its ground ever since. At $900 it remains one of the best value detectors available in New Zealand.

Long Range Detection

The R3nz uses Uniden’s proven long-range architecture – the same technology that made the R3 a standout performer in international testing. Single antenna, 360 degree detection, no directional arrows. If it beeps, ease off. Simple and effective.

NZ GPS Speed Camera Database

Every Uniden R3nz we sell comes with the New Zealand GPS camera database pre-loaded. Fixed speed cameras and red light cameras are covered. Keep your firmware updated and your R3nz will alert you before you reach them.

Zero-False Settings — Configured Before Dispatch

Before we send it out we open every box and adjust the settings to eliminate false alerts. Using factory settings, you’ll get alerted about weird Advanced Driver Assistance Systems in other cars, automated doors, road paint and other common false alert sources. With our settings, if it makes a noise — slow down. Don’t think about it.

Features

  • Long range detection
  • GPS database — fixed speed and red light cameras
  • Colour OLED display
  • Quiet Ride — speed-based auto mute
  • GPS auto-learn false alert filtering
  • Two suction window mounts included
  • 12V cigarette adapter included

How to Update Your Uniden R3nz

Already own an R3nz and are looking for a firmware or GPS database update? Updates are available directly from BluLink, the New Zealand Uniden agent.

Download the update tool, firmware and latest GPS database for the R3nz here.

Read the info carefully as there are different firmware and GPS files depending on the exact version of your R3nz.   Too hard?  We can help, or send it to BluLink directly.

Local NZ Warranty — Supported in Auckland

All Uniden products sold by NZRadars are sourced through the official NZ distributor BluLink, based in East Tamaki, Auckland. Local warranty support, no overseas shipping required.

Is the Uniden R3nz Still Worth Buying?

Absolutely. The R3nz was a game changer when it launched in New Zealand around 2018 — it brought genuine long-range GPS detection to a price point that hadn’t been possible before. Six years later it’s still one of the best value radar detectors available in New Zealand.

It’s compact, reliable, and does everything most New Zealand drivers need. GPS speed camera alerts, zero-false settings, solid range. Nothing in its price range comes close.

The main logical reason to step up to the R4nz is Bluetooth — useful if you want to pair with a helmet communicator on a motorbike via an app, or if you want crowd-sourced alerts via apps like Highway Radar or Radar Companion. If neither of those matter to you, save the a few hundred$ and put it towards something else.

Uniden R3nz vs Uniden R4nz — Which Should You Buy?

The R3nz and R4nz are similar detectors. The R4nz adds Bluetooth connectivity – useful for pairing with apps like Highway Radar or Radar Companion for crowd-sourced alerts. The R4nz also has a faster processor.

One important note: Uniden has confirmed a major firmware update for the R4nz later in 2026 that will add bus lane camera alerts, average speed camera zone alerts, and improved mobile speed camera detection. The R3nz will not receive this update. If those features matter to you, the R4nz is the better long-term investment.

  • Police Radar Frequency in NZ

    Ka radar, used in police patrol cars, operates on 34.7Ghz.  If you can isolate this frequency and switch off everything else, you’ll virtually eliminate any chance of false alerts.

    K band used in camera vans operates on 24.1 Ghz from a low-power radar transmitter.  This means that camera vans are very hard to detect reliably.

    The difference between K and Ka band is quite simple – read more about police radar frequencies in NZ here.

    It’s also worth the reminder that not all police cars have radar installed, normally just highway patrol cars.  They also don’t always have their radar turned on.  This is why your detector may not give you a lot of warning, it will suddenly blast a full-strength warning because the police just flicked their radar on the last second.  It’s tough to beat that sort of “hunting”.

  • There has long been talk of banning radar detectors, however this rumour has been circulating for nearly 20 years and there’s no evidence to suggest any New Zealand government will actually take action on the matter.

    Radar detectors are NOT illegal in New Zealand.

    There are a number of reasons why radar detectoes aren’t illegal here, as discussed here – read more.

  • The answer is BOTH. New Zealand Police use both radar and laser to detect speeding vehicles.

    Radar is more common though, with radar installed in police patrol cars, motorbikes, and fixed and mobile speed cameras.

    Laser is more accurate, but it can only be used by officers who are trained in its use and is used from a stationary, parked vehicle.  That said, laser can usually be transferred between police vehicles faster and easier, making it more financially effeciant for New Zealand police.
