Dexcom G6 CGM 30-day Trial

What is Dexcom G6 Continuous Glucose Monitoring?  

Continuous Glucose Monitoring (CGM) is a diabetes management tool that measures glucose levels 24 hours a day using a sensor inserted just under the skin. The device wirelessly transmits glucose readings in real time to a compatible smart device*.

The Dexcom G6 CGM gives the power to manage diabetes without fingerpricks^!  With just a quick glance at their smartphone or watch*, people with diabetes are able to see their current glucose levels, where they are heading and how fast they are moving.  It can also alert when levels soar too high or drop too low, so that appropriate actions can be taken in advance.

A real-time look at glucose levels can help to connect highs and lows to specific actions or meals and ultimately to help make informed diabetes treatment decisions.

The Dexcom G6 30-day trial is available at the special price of $379.50 incl. GST§ .

For any questions, contact us on 0800 500 226 or by using the form at the bottom of this page.

How does it work?

The Dexcom G6 CGM works through a tiny sensor inserted just beneath the skin, on the belly or arm. The sensor – connected to a transmitter – measures the level of glucose found in the fluid between the cells, also known as interstitial glucose. A glucose reading is transmitted wirelessly every 5 minutes to the display device* (compatible smartphone, watch or receiver). The Urgent Low Soon alert is designed to provide a 20-minute advance warning ahead of a low§§.

The 30-day New User Trial includes 3 Dexcom G6 sensors and 1 Dexcom G6 transmitter. The reusable transmitter will last up to 90 days and each sensor can last up to 10 days. Sensors are factory calibrated, meaning that the Dexcom G6 system requires no calibrations and ZERO fingerpricks^.

What are the benefits of CGM?


Whether it is about getting on with the day or just having a good night’s sleep, Dexcom G6’s customisable alerts can warn of a dangerous high or low before it happens, giving a head start to act…all with ZERO fingerpricks^. With so many diabetes management decisions to make at all times, CGM can assist at key moments throughout the day like before getting behind the wheel, when being physically active, in situations triggering stress or when going to sleep.



CGM can help detect the highs and lows that may be going unnoticed in between fingerpricks, and see in real time how the daily choices impact glucose levels to help understand what works best. It is also particularly helpful in case of hypoglycaemia unawareness.



Dexcom G6 offers outstanding accuracy in measuring glucose levels, no matter if high, low, rising or falling. The G6 is proven to lower HbA1c, reduce both hyper- and hypoglycaemia, and can increase time in a healthy glucose level range1,2.
