Note: While kiwifruit showed a lower constipation-relief percentage than prunes (45% vs 67%), the difference was not statistically significant. Patient satisfaction was highest for kiwifruit at 68%, compared with 48% for prunes and psyllium.
Tip: If you want the highest satisfaction and lowest side-effect burden, kiwifruit outperforms prunes and psyllium even if raw relief numbers look lower. The Michigan Medicine study confirms this trade-off clearly.

Where is Kiwi Crush in the supermarket?

Kiwi Crush sits in the frozen berries section of New World and Pak’nSave, typically alongside frozen fruit purees and smoothie packs. New World Aokautere confirmed on their Facebook page that Kiwi Crush arrived “by customer request” — a signal that demand drove retail placement rather than a marketing push.

Kiwi Crush at New World

The New World online store lists Kiwi Crush Tropical Kiwi in 5 × 70ml packs, confirming frozen-section availability. Check your local New World’s frozen berries aisle or use the stockist finder on kiwicrush.co.nz for real-time stock by location.

Other stockists like Pak’nSave and Countdown

Pak’nSave also stocks Kiwi Crush in its frozen aisles. Countdown availability varies by store; the official Kiwi Crush stockist finder is the most reliable tool for all retailers. For those outside NZ, the Kiwi Crush online store offers direct delivery.

Stock availability note: Frozen product placement can shift between visits. Calling ahead to the frozen aisle or checking the store’s online inventory before travelling is advisable for a first-time purchase.
TL;DR: Shoppers find Kiwi Crush in the frozen berries section of New World and Pak’nSave. Customer demand prompted New World to stock it, making it a request-driven retail item rather than a mass-market launch.

Is Kiwi Crush good for constipation?

Multiple clinical studies confirm kiwifruit-based products support constipation relief. The mechanism combines fibre-driven water retention in the colon with Actinidin, an enzyme that aids protein digestion and reduces gut discomfort.

Kiwi fruit’s role in relieving constipation

A 2023 Michigan Medicine clinical trial with 79 constipated adults found that 2 kiwifruits daily for 4 weeks achieved 45% relief — lower than prunes (67%) and psyllium (64%), but not statistically significantly different. Crucially, 68% of kiwifruit users reported satisfaction, the highest of any treatment arm in the study.

The same trial showed kiwifruit doubled weekly bowel movements with only 11% reporting bloating (compared with 36% for prunes and 33% abdominal pain for psyllium). A PMC multicenter RCT on 2 green kiwifruits daily confirmed clinically significant improvements in complete spontaneous bowel movements (CSBM), stool consistency, straining, and GI comfort.

“Consumption of 2 Zespri green kiwifruits per day is associated with a clinically significant increase in CSBM, improvements in abdominal comfort, straining and stool form.”

— Study Authors, PMC multicenter RCT

For elderly patients (over 60 years), a PubMed-reviewed 3-week study found that 1 kiwifruit per 30kg bodyweight increased defecation frequency and produced bulkier, softer stools.

Tip: If you experience constipation with a low side-effect tolerance, kiwifruit — and by extension Kiwi Crush — offers the best balance of relief and tolerability among natural treatments.
TL;DR: Clinical trials consistently show kiwifruit relieves constipation with the lowest side-effect burden of any tested natural treatment. Kiwi Crush inherits these benefits in a convenient frozen format backed by NZ-grown fruit.

What are the benefits of Kiwi Crush?

Kiwi Crush delivers the gut-health compounds from NZ-grown kiwifruit — Actinidin enzyme and dietary fibre — in a shelf-stable frozen sachet. The freezing process locks in nutrients without additives or preservatives.

Gut health advantages

The fibre in Kiwi Crush softens and bulks stool while Actinidin aids protein digestion and reduces gut discomfort, according to Kiwi Crush’s seniors page. Green kiwifruit increases water retention in the small bowel and colon due to fibre’s swelling capacity, as confirmed by the PMC multicenter RCT. Kiwi Crush also helps IBS sufferers reduce cramps and pain, though this benefit is medium-confidence.

Convenience of frozen format

Each 70ml sachet contains pulp from at least one medium-sized kiwifruit. The frozen format preserves Actinidin activity and fibre content without the need for preservatives. You can thaw a sachet in 30 minutes or blend it directly into a smoothie — no peeling or chopping required.

Note: Kiwi Crush is additive-free, suitable for children over 2 years, and available in Classic, Wild Berry, Tropical (green kiwi), and Gold (gold kiwi) flavours.

How to use Kiwi Crush?

Kiwi Crush sachets are designed for flexible daily use. The recommended approach mirrors the clinical dose of roughly 1–2 kiwifruits daily, adjusted to your comfort level.

Daily consumption frequency

For constipation support, one 70ml sachet per day is the standard starting dose — equivalent to at least one medium kiwifruit. The elderly study scaled to 1 kiwifruit per 30kg bodyweight, so a 70kg adult could aim for 2–3 sachets spread through the day for a full therapeutic dose.

Thawing and serving tips

  1. Remove a Kiwi Crush sachet from the freezer.
  2. Let it thaw at room temperature for approximately 30 minutes, or submerge in cold water for faster thawing.
  3. Snip the top and consume directly, or pour into a blender with your preferred liquid.
  4. For smoothies: blend with banana, yogurt, and a handful of spinach for a fibre-rich morning drink.
  5. For overnight oats: stir thawed Kiwi Crush into oats with milk and refrigerate overnight.
  6. For desserts: layer thawed puree with yogurt and granola for a gut-friendly snack.
Tip: Don’t heat Kiwi Crush — high temperatures degrade Actinidin, the enzyme largely responsible for its digestive benefits.
TL;DR: One sachet daily is the baseline dose; thaw in 30 minutes and consume directly or blend into smoothies and overnight oats. Avoid heating to preserve Actinidin activity.

What do you do with Kiwi Crush?

Kiwi Crush fits into both drink-based and food-based routines. Its puree texture makes it adaptable across recipes, from morning smoothies to evening desserts.

Kiwi Crush recipes

The puree works as a base for:

  • Green kiwi smoothie bowl with banana, spinach, and honey
  • Gold kiwi immunity smoothie with orange juice and ginger
  • Overnight kiwi oats with chia seeds and almond milk
  • Kiwi Crush frozen yogurt bark — spread on parchment and freeze
  • Kiwifruit overnight chia pudding layered with coconut cream

Versatile uses in cooking

Because the skin and seeds are removed, Kiwi Crush delivers a smooth pulp suitable for sauces, marinades, and sorbets. The Kiwi Crush official site highlights that the freezing process locks in natural goodness without additives.

“Prunes and psyllium proved to be the most effective at relieving individuals from chronic constipation. And among the patients assigned to these treatments, the goal was reached by 67% and 64%. Overall, 48% of patients in the psyllium and prune groups were happy with their treatment, while 68% expressed satisfaction with kiwifruit.”

— Dr William Samuel, Gastroenterologist, Michigan Medicine Health Lab

TL;DR: Kiwi Crush works in smoothies, overnight oats, chia puddings, and frozen desserts. Its smooth pulp without skin or seeds makes it more versatile than fresh kiwifruit for cooking and blending.
