"But with anything that's significant I would be surprised and concerned that they hadn't consulted iwi. They would feel it was their duty and most people would take it on as an important part of the project."
Auckland's Mt Eden landmark came to mind as one example where local iwi were consulted about changes, he said.
"The mountain is a volcano and they're very valuable places for local iwi. If the landscape architects didn't consult with iwi there is just no way they'd get away with it. It just wouldn't be allowed. They would have to have a really close association with iwi."
Te Mata Peak, a Hawke's Bay landmark loved by locals and visitors alike, commanded such respect, he said.
"The mountain is a person, in effect, so you give it more respect. To me any place Pakeha think is amazing, is usually really important to Maori as well. So I would be shocked if they hadn't fully considered or engaged the local iwi about it."
