Auckland Mayor Phil Goff said while reversing the error would likely incur costs, the "magnificent" pōhutukawa should be left alone. "It's equally my view that you cannot allow a tree of this heritage nature - that we've already scheduled once - to be destroyed inadvertently. That is not an option from my point of view ... That view is shared by others around this table," Goff said.
