When do I receive my bond back?

Within 7 working days from the day the unit arrives back to me. If you'd like to check the TENS unit has arrived back to me please check your NZ Post tracking. If you'd like to check your bond has been paid back, please check your credit card and emails (Junk & Clutter folders too). Once you receive email confirmation that the bond has been returned, allow 2-3 days to appear in your account.

What should I do if I think my TENS has a fault?

As soon as you receive the TENS machine, check all components. Test everything is working correctly. When testing the TENS you must remove the electrodes from the plastic sheets and place them onto your body. The TENS will not work unless you place the sticky electrodes onto yourself. 

Our TENS unit are VERY reliable, but if you are having some issues visit our TECHNICAL HELP page.

If you believe there is a fault with the unit or something is missing please call us immediately for assistance on 021 054 0251. Usually it is a very simple fix.

Is one set of electrodes enough? 

Yes, if you look after the sticky electrodes then one set is enough. You receive one set of electrodes with your TENS. If you remove the electrodes (to get into the shower or pool) then ask your birthing partner to carefully place the sticky side back onto the plastic sheets, ready for reapplication. If you are concerned that you'll need more than one set you can purchase extra sets from this website.

How does TENS work? 

TENS units supply gentle, electrical impulses through your skin via four self-adhesive electrode pads positioned on your back.

These gentle impulses attack pain in two ways:
1. by stimulating the release of endorphins, the body’s own pain-relieving hormones
2. by stimulating the nerves to block the slower-moving pain messages coming from your cervix and womb before they reach your brain.

What does TENS feel like?

TENS feels like a pleasant tingling sensation on the skin where the electrode pads are placed.

How is a labour TENS used?

Self adhesive electrodes are placed on the lower and mid back. You switch on the TENS and turn it up until you feel the tingling. You can increase the intensity to ride out each contraction. The unit can be worn as needed for as long as needed. Labour TENS is best used at home when the contractions begin and continued for up to several hours after birth. Labour TENS will help with uterine contractions after birth and whilst breast feeding.

When do I start using the Labour TENS?

The earlier the TENS is used, the better. This gives your body time to build up natural endorphins. You can use the TENS machine right through your entire labour or alternate the TENS with other forms of pain relief.

Can I use the TENS machine before labour begins?

Yes, once you have reached 37 weeks of pregnancy, you can use the TENS machine for pain relief. Please do check with your midwife first. If you'd like to use the TENS machine for pain relief prior to 37 weeks, please check with your midwife.  

Can I try out the TENS machine when it arrives?

Yes! It is important for you to check the TENS is in full working order and you have everything you need. Please do this as soon as your TENS arrives. You or your birthing partner can try out the TENS on your leg or arm. To try out the TENS you need to stick the electrodes onto your body. A good place to do this is your partner's upper and lower arm. You need at least two electrodes stuck to the skin (black and red).

Is TENS safe?

Yes, very safe. Labour TENS units are specifically designed for labour. However there are a few precautions. Do not use over broken or desensitised skin. Do not use before 36 weeks unless approved by your doctor. Do not use in water. Seek advice from doctor if you have unstable epilepsy or a pacemaker.


I would like a water birth – can I use a Labour TENS?

Yes, although NOT whilst in the water. You need to REMOVE the TENS BEFORE you enter the water. While you are in the water your Birthing Partner can be responsible for preparing the TENS unit so it can go straight back on when you come out of the water.

Where do I place the electrodes? 

You don't need to be absolutely exact when it comes to applying the electrodes on your back. The top two electrodes should be placed either side of your spine with the top of the electrodes in line with your bra strap. The bottom two should be placed with the bottom of the electrodes in line with the top of your where your buttocks meet. See an instructional video here.

Can I take the TENS into hospital with me?

Yes. The midwives and doctors are usually very happy for women to use TENS. Check with your midwife or doctor if you are unsure. You may need to turn the TENS off temporarily if using electronic monitoring equipment.


What type of TENS unit should I use?

Make sure you use a TENS unit specifically designed for labour. These are called an OBSTETRIC or LABOUR TENS and they work differently to a regular TENS machine. They have two settings and a boost button. You need two settings, one for mid-contraction (higher setting) and one for between contractions (lower setting). You need a boost button which you can simply press (turn on) when a contraction comes on and press again (turn off) once a contraction has subsided. Also make sure the unit is modern and comes with brand new electrodes which you can put on and take off again. The unit should come with batteries and instructions. Our BabyCare Elle TENS units are modern, reliable TENS units with all these important features and they come with everything you need. Features and benefits include:

Easy to use push button control
Our TENS units have a hand held control to change the stimulation mode from LOW frequency bursts to HIGH frequency stimulation. The low frequency is used during rest periods (between contractions). As soon as a labour contraction is felt strongly you can change the mode to high frequency stimulation. Once the contraction has subsided you can change the mode back to low frequency.
Easy to follow instructions
Enclosed with your TENS unit you will find a small booklet with instructions on how to use your TENS unit. The diagrams are clear and simple to follow. We also have instructional videos to help you understand how TENS works and how to use it.
Small and Lightweight
Our TENS units are small and light-weight. You can move around easily without feeling restricted in any way. They also have a clip and lanyard so you can either attach the TENS to you waistband or wear it around your neck.

Where can I hire a TENS unit?

You can hire one from NatalCare Naturally! The hire fee includes FREE overnight door-to-door courier service anywhere in New Zealand (non-rural addresses) and FREE return postage. When booking you can select the date you’d like the TENS dispatched to you.

When should I book a TENS?

Once you have an idea of your due date, you can book a TENS anytime. You select the date that suits you for the dispatch. Most people book during the 2nd trimester, but it's a good idea to book earlier if you wish. If you have left it to the 3rd trimester or even a couple of days before your due date, then go ahead and book on-line and a unit will be  available for immediate dispatch.

Have I left it too late to book?

If a booking is made and paid for by 2.30pm on a regular working day (Monday to Thursday), then we can dispatch a unit on an overnight service the same day. Target delivery to main centres is overnight. Rural deliveries can take at least 3 days longer. If you live in Christchurch, you can select click and collect.


What if I need the TENS unit longer? or if I go over my due date?

We will simply deduct $10 per full week for each week longer you require the unit. We deduct this from your bond before returning it.

How do I track and trace my TENS?

Once we dispatch your TENS unit you will be sent a tracking number.  If you would like to track your parcel you can do so with the tracking number provided to you by email at www.nzpost.co.nz (for Courier Post). If you are concerned your parcel has not arrived you can contact NZ Post Customer Services on 0800 501 501.  If you live in a rural area then your parcel will be passed onto your local rural driver and delivery will take 2-3 days longer to reach you. 

What happens if I have lost my TENS machine?

If your TENS machine has been lost please advise us immediately. If you delay contacting us you may be liable for late fees. An invoice will be sent to you which covers the replacement cost of the unit (less bond you have paid). 

What happens if I have returned the TENS but is it lost in the post?

In the unlikely event you have returned your TENS machine and it has been lost in the post, then you will need to work with Courier Post to try and locate the parcel. If the parcel is deemed lost the you will need to submit a claim with New Zealand Post. We can assist by providing you with evidence of the value of the goods. You will be sent an invoice from NatalCare Naturally 8 weeks after the date the unit was due back. This will give you time to make the claim.
