Tauranga businesses are being urged to put on their capes and join forces for what organisers are calling a "bloody awesome" event this Wednesday, April 5.

The goal is to see how many lives can be saved across the Bay of Plenty in a day by calling on the public to donate blood.

"Every week, more than 5,000 blood donations are needed here in New Zealand, and with less than 4 per cent of Kiwis currently donating, we are often behind where we need to be to support our people in need," says an event spokesperson.

"That's why Priority One, who exist to improve prosperity in Tauranga Moana, are rallying our community to come together and make a difference to those who need."

On who is able to come along and participate, the event spokesperson says Priority One is inviting all members and local businesses to "get their teams together" and see how many lives can be saved "in the Bay in a day".

"Donating blood is a simple and quick process that can have a huge impact on someone's life. In fact, just one donation can help save up to three lives. By taking just a few minutes out of your day to donate, you'll not only be helping those in need, but you'll also be contributing to our collective effort to ensure that our local community has a reliable and sustainable blood supply."
