"The New Zealand Geographic Board has recommended the spelling of Wanganui be changed to include the controversial 'h'."
"In the end we could not overlook the fact that Wanganui is not correctly spelt and it is a Maori name that is of significant cultural importance," Dr Grant said.

Good result, now get ready for the bleating of that nobody laws.
