We spent an incredible few months at Shanon's place and it has been one of the highlights of our time in New Zealand. Waiwera is stunning, the beach is amazing and about a three minute walk away from the home. Wenderholm Regional Park is a 10 minute walk away and has some beautiful trails with easy and moderate hikes.
If you stay here I'd recommend getting up early to enjoy the unreal sunrises at the beach and checking out the Sunday market in Orewa. There are frequent buses between Waiwera and Orewa (larger town with grocery stores, cheap 10 minute ride away). The home has fast wifi and nice amenities, Shanon was fast to respond to any messages we sent, good communication. This place is perfect, we're missing it already!
