For Grace Jack, living in a digital world is normal.
The 17-year-old Rangitoto College student doesn't know a world without computers or cell phones.
"I can't imagine the world without them. I usually use my phone for everything - even the alarm on it is what wakes me up.
"I wouldn't know how to use a normal alarm.''
The year 12 student said she communicated with her friends a lot via various social media apps - including Facebook, Snapchat and Instagram.
