Stace, Anika and Dave, from The Hits, were to emcee the event.
Those who could not make it were able to tune in to 97.7FM (The Hits) from 7pm to listen to Kiwi songs synched to the fireworks.
Stacey Morrison, from The Hits, told the Herald the event was a great way to celebrate Matariki.
"It's a nice way to look at what New Brighton offers as a setting. I think we've got this backdrop of a beautiful night sky and we all just enjoy these fireworks."
She said different iwis would quite often recognise whatever star was their reference for the new year.
Ngāi Tahu, in the south, often recognises Puanga, another star that is particularly bright in the south.
"The beautiful thing about Matariki is that it is something ancient that was nearly lost to us that we've been able to reclaim as this tradition.
"It's really about looking at the year that's passed, being grateful for the harvest and everything that we can get from our environment and everything we've survived in the last year. As well as planning for the year ahead and give our wishes to the wishing star Hiwai-i-te-rangi."
Morrison said it was important to celebrate the Māori new year as it is unique to New Zealand.
"It's relevant to our seasons, in these cold winter months it is time to look at things that are relevant to us."
The Matariki star cluster is well known throughout the world and at different times of the year can be seen around the globe. It is one of the brightest clusters in the sky, containing hundreds of member stars.
It has different names around the world. In English, it is called by its ancient Greek name, Pleiades or the Seven Sisters. In Hawaiian it is Makali'i, "eyes of royalty", and in Japan it is Subaru, meaning "gathered together".
