How to Choose a Car Seat
Which is the right seat for your little one? Choosing a car seat can feel overwhelming. Your choice is more than just a purchase; it's an investment in your child's safety and comfort. Are you looking for a capsule, a convertible, a booster seat or an all in one? And how do you know where to start? Buckle up as we lay out the different types of seat to help you figure out what’s right for your whānau. Capsule Car Seats Best for: Newborns to approx. 12 months (up to 13kg depending on the brand)What they are: Rear-facing, portable infant car seats that easily lift in or out of the car. Most of the capsules we sell clip onto a base (sold separately) that stays installed in your car. Others have a baseless install either by Isofix or car seatbelt. Why parents love them: If you choose a capsule that's compatible with your stroller, you can transfer your sleeping baby for car to stroller without waking them They're easy to carry with a handle Most work with a base that stays in the car - simple click and go. Things to consider: You’ll likely only use it for the first year. Weight matters – some are much easier to carry than others. Great options to compare: Nuna Pipa Next – lightweight (only 2.8kg) and super portable. Nuna Arra Flex – features three recline positions - including a near-flat 157° recline. Maxi Cosi Pebble 360 Pro – ergonomic recline, 360° base for easy loading. Nuna Pipa Urbn – ideal for swapping between cars or rideshares, it has built-in Isofix, no base required. Nuna Cari Next – a lie-flat carrycot that’s also a car seat – perfect for naps and spinal support. Convertible Car Seats Best for: Birth to approx. 4 years (or longer depending on the seat)What they are: Seats that start rear-facing and convert to forward-facing as your child grows. Why parents love them: Cost-effective – you’ll use it for several years. Often more spacious and padded than a capsule. Things to consider: Not portable – it stays installed in the car. Some seats rotate on a base, so you can turn them towards the door to make buckling in easier Check your car - do you have Isofix points or do you need a seat that can be seat belt installed? Great options to compare: Nuna Todl Next – works with a rotating base for easy access. Nuna Rylo – built-in 360° rotation, no separate base required. Nuna Rava - seatbelt installed, and known for its simple installation, generous legroom, and plush comfort. Ideal for families who want a long-lasting seat without the need for a base or Isofix. All-in-One (Convertible + Booster) Best for: Birth to approx. 11–12 yearsWhat they are: Car seats that transition from rear-facing to forward-facing to booster seat. Why parents love them: One purchase that lasts for years. Ideal for parents who don’t want to keep upgrading. Things to consider: Not portable – stays in the car. No rotating options available. Great options to compare: Nuna Exec – rear-facing from birth, forward-facing to booster mode up to 148cm / 54kg. Britax One4Life Slim – rear-facing to booster mode up to 160cm / 54.4kg. Booster Seats Best for: 4+ years (or as per height and weight guidelines)What they are: Forward-facing seats that position the vehicle seatbelt properly across your child. Why parents love them: Simple to use and install. Gives older kids a good seat height and a view out the window. Often more compact. Things to consider: Only suitable once your child meets minimum size requirements. Great options to compare: Nuna LUMN – harnessed car seat that transforms to a belt positioning booster Nuna AACE LX – adjustable height, recline, and side impact protection. Britax Skyline – affordable, comfortable, and lightweight. Axkid Up – has a patented raisable seat to elevate your child to better align with the vehicle seat belt Other Key Considerations When Choosing a Car Seat Car fit: Not all seats fit all vehicles – check for compatibility, especially if fitting multiple seats. Ease of use: Consider rotating seats if you struggle with lifting your child in and out. Installation method: Isofix is quicker and easier, but seatbelt installs offer flexibility for older vehicles or travel. However Isofix does have lower weight restrictions (generally around 18kgs). If a seat allows for both Isofix and seatbelt installation it can pay to opt for Vehicle Seat Belt installation as it eliminates having to switch installation method once weight limits are reached. Longevity: Weigh up whether you want a dedicated seat for each stage or one that adapts as your child grows. Need Help Choosing?

Tips & Tricks - Cleaning your Carseat
How to Keep Your Car Seat Clean (and Looking Like New!) Parents and caregivers know that washing can quickly take over your life when you’ve got little ones around – especially when it comes to car seats! Kids, being kids, seem to have a knack for turning a spotless, brand-new car seat into a treasure trove of crumbs, spills, and, well, the occasional bodily fluid. While it would be ideal to ban all food and drink from the car seat (let's face it, that’s easier said than done!), prevention is key. A full-sleeved bib worn over the straps can help catch any messes before they even get the chance to make a mark. If a major mess happens (think: vomit, diaper leaks, or spilled drinks), the sooner you clean it up, the better. In between those big cleans, a quick vacuum once a week can keep things under control and prevent crumbs from piling up. For extra protection, consider using protective car seat covers or mats to catch any messes that could cause long-term damage to your car. Here are some simple steps to keep your car seat looking fresh and clean: 1. Vacuum Your Seat Give your seat a quick shake to loosen any crumbs or debris, then vacuum up the mess before removing the car seat for a deeper clean. This will stop any stray bits from making a mess as you go! 2. Remove and Wash the Car Seat Covers Start by checking your car seat’s instruction manual for cleaning guidelines. Many car seat covers are machine washable, but some may require hand washing. Be sure to note any special instructions about detergent, water temperature, or removable parts. Pro tip: Take a few photos or a video as you remove the covers. This can be a lifesaver when it's time to reassemble! A gentle, mild detergent or just soap and water are typically your best bet. Avoid bleach or harsh chemicals, as these can damage or weaken the fabric. When it comes to drying, line drying is your safest option, as most car seat covers can't go in the dryer. Give them plenty of time to air out and dry completely. 3. Clean the Harness & Straps Use a non-abrasive cloth and warm water to spot clean the harness and straps. Follow your manual’s instructions, as some manufacturers allow using soapy water, while others may not. 4. Clean the Buckles Buckles are critical for keeping your child safe, so avoid submerging them in water or using any lubricants. Instead, spot clean them with warm water and a soft cloth, keeping them free from soap or cleaning products. 5. Clean the Shell Vacuum the car seat shell to catch any loose bits, then use an old toothbrush or cotton bud to get into those tricky nooks and crannies. A damp cloth can help wipe down any sticky or dirty areas. Make sure the shell is fully dry before putting everything back together. 6. Reassemble Your Seat If you took photos or videos while disassembling, now is the time to refer back to them! Check your manual to ensure all parts are correctly reassembled, and give the harness and buckles a final check to ensure they’re securely fitted and ready for your little one. Note: This guide is intended to help with your car seat cleaning routine, but always follow the manufacturer’s specific instructions in your car seat manual to keep your warranty intact.

Carseats Standards in New Zealand
Under New Zealand law, the driver is responsible for making sure all children under seven years of age are using a child restraint (car seat) that’s appropriate for their age, size, and development. Keeping your child safe is the number one priority. As a guide, from 0-2yrs, most babies should be in a rear-facing capsule or car seat, from two to around four or five they should be in a front-facing restraint, and after that, they should stay in a booster seat until they’re 148cm tall. Read our full guide to choosing a car seat here New Zealand car seat standards Every car seat that is sold or used in New Zealand has to be manufactured to a standard that complies with our minimum safety standards. You will find the car seat safety standard displayed as a sticker or a label on the shell of your child restraint. This will indicate which safety standard your car seat was manufactured to. When looking at car seats, you may identify a variety of different stickers: 1. The joint Australian, and New Zealand standards. This sticker can be identified as AS/NZS 1754. If you have an Australian standard car seat with this sticker identification it can be bought into New Zealand and used here. 2. The European Standard can be identified by a sticker reading ECE R44/04 or UN R129 and/or i-size. A European standard car seat with a sticker showing these numbers is legal for use within New Zealand. 3. The US standard child restraints can be identified with the code FMVSS 213. Some child restraints that are manufactured to the US standard are approved for use within New Zealand, but it is important to note that not all are. Child restraints that are manufactured to AS/NZ and European standards are independently tested to achieve the certification that allows each car seat to be used within New Zealand. However, car seats that are manufactured to the US standard are self-certified. This is why independent testing of US standard car seats must be run by the certification agency - Bureau Vista - prior to being used here in New Zealand. Once it has been approved for use here, each car seat will have a yellow compliance sticker applied. Note: If you buy a car seat in America, it won’t be compliant for use in NZ. Even if the exact same model can be purchased here, one bought in America won’t have the required compliance sticker and therefore isn’t legal for use in NZ. 4. You won’t often see the Japanese Car Seat Safety Standard here. It is only approved in NZ for child restraints that are built into a vehicle – eg a built-in booster seat that can’t be removed from the car. Note: If the car seat standard sticker falls off, or is no longer able to be read (this could be because a car seat is old and has expired), the restraint is not compliant, and therefore it is not legal for use on our roads. I’m Visiting NZ – Can I bring my own car seat? When visiting New Zealand from overseas you can bring your own child restraint only if it carries either the AS/NZS 1754 or the ECE R44 / R129 safety standard sticker.
