Whitianga Summer Concert is being cancelled due to the severe weather.

In a post to Facebook, organiser Greenstone Entertainment says after the continued disruption around road access in and out of the Coromandel Peninsula, and information from authorities, they "made the heartbreaking decision" to cancel the upcoming event.

"This was our only option given our priority must always be to protect the health and safety of both our crew that are tasked with setting up and delivering the show, and of course all our concert goers who predominantly travel to get to the show," the post reads.

"Concert goers who purchased tickets online will be contacted directly by Moshtix. You don't need to do anything; your ticket(s) will be automatically refunded back to your credit card used to purchase and they'll let you know when this has been done.

"Please allow up to 30 days for the funds to return to your account. If your card details have changed, please wait for Moshtix to contact you directly regarding this.

"Fans who purchased tickets at local outlets, will be contacted directly by Greenstone Entertainment and will receive a refund within 30 days."
