"There is currently no event in Rotorua on Waitangi Day. They celebrate in London, Sydney, Gold Coast, but not here."
Some people commenting on the page agreed with Coffey, one saying she couldn't believe there were no events in Rotorua.
"We searched for things to do in Rotorua but there was nothing. Couldn't believe it. So we went to visit with our Tuwharetoa whanaunga and enjoyed the concert," she said.
While others wanted to celebrate Waitangi Day but disagreed with merging the two.
"Lakeside is an amazing event and should be left to itself. Waitangi Day should also be celebrated on its own day for its own special reason. No to a merge," one person wrote.
When asked last week, Rotorua mayor Steve Chadwick, who is a member of the Lakeside Concert Charitable Trust which runs the annual concerts, said she had asked the trust to consider changing the date to Waitangi weekend.
Trust chairman Ian Edward said he was open to considering the idea.
