Mrs Hook will be taking part in Walk 2 D'Feet Motor Neurone Disease in honour of her mother.
The walk - held in Whanganui this year for the first time - will began at 10am on September 25, from the i-Site on Taupo Quay. Registration opens at 9am.
Mrs Hook said the walk is approximately 5km and is on flat terrain along the Whanganui River. Kids are welcome. The walk will be wheel-friendly for wheelchairs, prams and strollers. Leading the walk will be the West Coast Bombers roller derby team.
Participants can register on the day or on the website, http://walk2dfeetmnd.co.nz. It costs $15 per person, with half the money going to support Motor Neurone Disease in New Zealand, and the other half going to Motor Neurone Disease New Zealand to help it continue its work.
Walk 2 D'Feet marches will be held throughout New Zealand.
