A man is due to appear in court today charged with the murder of Wanganui toddler Karl Perigo-Check.

Wanganui freezing worker David Bourke will tomorrow be charged with murdering his brother, police say.

Most New Zealanders prefer the retention of the name Wanganui and no change to Whanganui, a poll released today says.

Michael Laws is embroiled in fresh controversy after an email exchange over the 'h' in Wanganui went viral.

Wanganui's mayor said Pita Sharples did not understand "any culture that is not Maori", after the Maori Party co-leader called for Wanganui residents to accept its new name.

Iwi say Laws approached them about a compromise on putting an "h" into the city's name, but was told unequivocally there was none.

Mayor Michael Laws calls the decision to include an 'H' in Wanganui "a grievance and a wrong ...perpetrated on the great majority of the people of Wanganui".

Wanganui Mayor Michael Laws remains confident the Government will reverse the Geographic Boards' decision to insert the letter H in Wanganui.
