Mermaid Birthday Party

Have you been swimming round in circles looking for the best NZ mermaid party supplies? It's time to come ashore as we have everything you need in our mermaid party box. Our party boxes include all of the mermaid decorations, tableware and party supplies you need to host an amazing mermaid themed party.

Mermaid Theme Party

Mermaid parties are a great kid's birthday theme and are especially popular with girls aged 3-10. With so many beautiful pinks, purples and green party supplies available, its easy to get carried away with your mermaid party shopping!

Mermaid Party Supplies NZ

Mermaid decorations are filled with shells, seahorses, fins, scales and tails ideal for transforming any room into an underwater paradise. Simply match the mermaid balloons to the mermaid garlands and tableware and you'll have the most delightfully themed party. For extra impact, we highly recommend using a matching balloon garland - a great way to fill a room with colour.

Mermaid Party Food

When it's time to feed your half child, half fish guests, the choices of mermaid party food are endless. Serve up mermaid tail cupcakes, crab croissants, clam or oyster cookies or blue coloured popcorn or sweets. Each item will look beautiful on our cute mermaid shell plates and napkins.

Mermaid Cake

Mermaid cakes are a delight to look at and so much fun to make. A great option is to wrap your cake in coloured fondant scales. Simply layer them over the top of each other to give that fish scale look. A mermaid cake topper can either be moulded and created yourself, or alternatively you can insert a doll into the top.

Mermaid Cupcakes

Mermaid cupcakes are super easy to make with our mermaid cupcake decoration kit. Bake or buy, then insert each cupcake into the set of beautiful pink and purple cupcake wrappers. To decorate, the kit includes a set of mermaid tails and scallop shell toppers.

Mermaid Party Ideas

If swimming around your newly decorated underwater paradise isn't enough entertainment for your scaled guests, then 'pin the tail on the mermaid' will keep the excitement going. A fun take on a classic party game, each pack includes a blindfold and mermaid tail stickers. For those that are a bit more adventurous you can try a mermaid tail 'sack' race where your guests need to race with their legs practically tied together - a great way to experience life as a mermaid on land!

Mermaid Party Favours

To end the underwater adventure with a splash your guests will love our mermaid tail treat boxes. Uniquely mermaid tail shaped they are sure to encourage squeals of glee. Fill them with mermaid treats, stickers and goodies that your little mermaid guests will take home to cherish.

Have you been searching across the ocean and under the sea for the perfect mermaid decorations? We understand how much work it is find all the right matching party supplies in one place.
