If you're shopping for a newborn in New Zealand and the sizing labels are making your head spin, you're not alone. Size 00 is one of the most searched terms by Kiwi parents preparing for those early weeks, and yet it's rarely explained clearly. At Zoe Sage, an Australian brand shipping directly to New Zealand, we've put together this complete buying guide to help you navigate size 00 clothing, pick the right bibs, and build a newborn starter kit that actually gets used.
Here to shop rather than research? Browse our Baby Bibs collection. The guide below covers what to look for, wherever you buy.
We ship all orders from our Australian warehouse, fully tracked, with free NZ shipping on orders over $150 NZD. So whether you're stocking up before baby arrives or grabbing a gift, you'll know exactly where your parcel is every step of the way.
What Is Baby Size 00 in NZ?
In New Zealand (and Australia), baby clothing follows a sizing system based on age and approximate weight, not the same numerical sizing used in the US or UK. Here's a quick reference so you can shop with confidence:
- 0000 , Newborn, roughly 2,4 kg (up to about 50 cm)
- 000 , 0,3 months, roughly 3.5,6 kg (up to about 56 cm)
- 00 , 3,6 months, roughly 6,8 kg (up to about 62 cm)
- 0 , 6,12 months, roughly 8,10 kg (up to about 68 cm)
- 1 , 12,18 months, roughly 10,12 kg
So size 00 covers roughly the 3 to 6 month window, though every baby is different. Some chunky newborns bypass 0000 entirely and head straight into 000. Others are still comfortable in 000 at four months. When in doubt, size up. Babies grow fast and a slightly roomy fit is always more comfortable than something too snug.
Why NZ Parents Often Get Confused by 00 Sizing
The confusion usually comes from comparing labels across brands or shopping from international retailers. A "3 months" label from a US brand often corresponds to our 000 rather than our 00. If you're shopping Zoe Sage from New Zealand, our sizing follows the standard Australian convention listed above, so the chart above applies directly.
For a deeper look at how sizing works for the very youngest babies, our guide to 0000 baby sizing in NZ covers the newborn end of the scale in detail.
Choosing the Right Bibs for a Size 00 Baby
Bibs are one of those items you'll genuinely go through in volume. Whether it's dribble, reflux, or the enthusiastic mess of starting solids, the right bib makes a real difference. For a 3 to 6 month old in size 00, you have two main options: muslin bibs and linen bandana bibs. Here's how to choose between them.
Organic Muslin Baby Bibs: Soft, Absorbent and Gentle
Muslin is the gold standard for newborn and early baby products for good reason. It's lightweight, breathable, gets softer with every wash, and is gentle enough for sensitive skin. Our Organic Muslin Baby Bibs come in packs of five and are sized to suit babies from birth through to the size 00 stage and beyond.
If you're building your starter kit, we'd recommend grabbing at least one five-pack. The Organic Muslin Baby Bibs - Golden Harvest 5 Pack is a warm, earthy tone that works beautifully across genders, while the Organic Muslin Baby Bibs - Lavender Blush 5 Pack is soft and understated for those who love a muted palette. The Organic Muslin Baby Bibs - Earth and Sky 5 Pack offers a mix of nature-inspired tones, and the Organic Muslin Baby Bibs - Dusty Dunes 5 Pack is a perennial favourite for its versatility.
Five bibs per pack sounds like a lot until you're three days into a particularly dribble-heavy patch and you've already burned through four of them by lunchtime. Stock up.
Linen Bandana Dribble Bibs: Stylish and Practical
Linen bibs are a step up in texture and visual appeal. They have a slightly more structured look than muslin, making them a popular choice for photos, outings, or when you want something that looks put-together even in the chaos of early parenthood. Linen is breathable and becomes beautifully soft with use.
Our Linen Bandana Dribble Bib - Little Leopard is one of our most-loved prints, a modern animal print that works across a range of outfit colours. The Linen Bandana Dribble Bib - Charcoal is a classic neutral that goes with absolutely everything. Both feature a bandana cut that sits neatly at the neckline and catches dribble efficiently without being bulky.
You can browse our full range of dribble bibs and find the styles that suit your baby's wardrobe. If you're a first-time parent wondering why your 3 month old is suddenly soaking through three bibs a day, our article on why babies dribble explains what's actually happening developmentally, which is genuinely reassuring to know.
Muslin vs Linen: Which Should You Choose?
Here's a simple comparison to help you decide:
| Feature | Organic Muslin Bibs | Linen Bandana Bibs |
|---|---|---|
| Absorbency | Very high | Good |
| Softness | Ultra soft from wash one | Softens over time |
| Style | Classic, simple | Modern, structured |
| Best for | Heavy dribble, reflux, everyday use | Outings, photos, lighter dribble |
| Pack size | 5-pack | Individual |
Our honest recommendation: start with a five-pack of muslin bibs as your everyday workhorse, and add a couple of linen bandana bibs for those days when you want something a little more polished. If your baby is a champion dribbler, you might find our post on what to do when baby keeps pulling their bib off very useful.
Building a Newborn Starter Kit for NZ Families
Beyond bibs, here's what we'd consider the practical essentials for a newborn through size 00 stage. This isn't an exhaustive list, it's the stuff that actually gets used daily.
Wrapping and Swaddling
Wrapping a newborn can help them feel secure during sleep. According to Red Nose Australia, lightweight cotton or muslin wraps are recommended for safe wrapping, and you should stop wrapping at the first signs of rolling, or at 3 months, whichever comes first. Our Organic Cotton Muslin Swaddle Wrap is breathable and easy to use, and the Stretchy Baby Swaddle Wrap offers a little more give for wriggly newborns.
On the topic of safe sleep: Red Nose advises keeping baby's head and face uncovered during sleep. To check if your baby is at the right temperature, feel their tummy or back. Cool hands and feet are perfectly normal. If baby feels hot, sweaty or clammy, remove a layer. Dress them as you'd dress yourself for the room.
Nappy Change Essentials
The Portable Nappy Change Clutch is a practical addition that keeps everything in one place for changes on the go. Pair it with a pack of Organic Muslin Baby Wash Cloths, Soft & Gentle for Newborns for gentle, reusable cleansing, and you've got a compact change kit ready to toss in any bag.
Feeding and Nursing
If you're breastfeeding, the Multi-Use Nursing & Breastfeeding Cover offers privacy and versatility, working equally well at home or out and about. The Washable Bamboo Nursing Pads (8pk) are soft, moisture-wicking, and reusable, a much more sustainable option than disposables. For general breastfeeding support and guidance, the Australian Breastfeeding Association is an excellent resource for NZ families as well.
On-the-Go Organisation
The Pram Bag Caddy Organiser keeps your essentials within reach without digging through a giant nappy bag. It's one of those products that seems like a small thing until you've tried life without it. The Grab & Go Mum Ready Duo Bundle is also worth a look if you want a head start on the organisation front.
Blankets and Layers
The Cotton Classic Knit Baby Blanket and the Cloud Bubble Baby Blanket are both popular choices for pram outings and tummy time. The Merino Wool Newborn Cocoon Baby Wrap is particularly lovely for the earliest weeks, as merino is naturally breathable and temperature-regulating, helping baby adjust to cooler NZ mornings without overheating. One practical reminder from Red Nose: always keep blankets away from baby's face during sleep, and ensure the sleep space is clear.
Shopping from NZ: What You Need to Know
Zoe Sage is based in Australia, and all orders are dispatched from our Australian warehouse with full tracking, so you'll always know where your parcel is. We offer free shipping to New Zealand on orders over $150 NZD, which makes it easy to stock up across a few categories in one go.

Frequently Asked Questions
Is size 00 the same in NZ and Australia?
Yes. New Zealand and Australia use the same sizing convention for baby clothing. Size 00 covers approximately 3 to 6 months, or roughly 6 to 8 kg. Always check the individual brand's size guide, as there can be minor differences between labels.
How many bibs do I need for a size 00 baby?
Most parents find that 8 to 12 bibs is a workable number for daily use. If your baby dribbles heavily or has reflux, you'll be grateful for more. A five-pack of muslin bibs plus two or three linen bandana bibs gives you variety and enough volume to get through laundry cycles without running out.
Does Zoe Sage ship to New Zealand?
Yes. We ship all orders from our Australian warehouse with full tracking to New Zealand. Free NZ shipping applies to orders over $150 NZD. Delivery times vary, but you'll receive tracking details as soon as your order is dispatched.
When should I stop swaddling my baby?
Red Nose recommends stopping wrapping at the first signs of rolling, or at 3 months, whichever comes first. This is an important safety guideline. If you're unsure, speak with your Well Child Tamariki Ora nurse or GP for personalised advice.
