Simon Mackenzie, the group chief executive of Vector sits down with Vaughn Davis on Sunday Social.

Simon talks to Vaughn about the exquisite lights on the harbour bridge, and the way that Vectors light display made up of 90,000 lights came to be.

The Vector Harbour Bridge light display is solar powered and references aspects of Maori culture such as Hei te Ao Marama (the future world of light).

There is still time to catch the widely popular show.

"there's been a great crowd around Auckland"

The lighting show can be seen from a variety of places across Auckland such as Devonport, Mt Eden and Te Atatu.

Digital consultant Cate Owen talks to Vaughn Davis on Sunday Social about the Apps of the Week.

Cate looks at Huji Cam, Celebrity faces swaps as a new adult film trend and about "social ranking" in daily life.

Huji Cam is a camera app that makes your camera look like an old-school disposable camera. Are we a fan?

Cate also looks at the latest trend in adult videos - Face swapping. Someone has used the face swapping ability of apps like snapchat to take celebrities faces and convincingly map them onto porn stars bodies. The technique is known as "deepfakes" and had led to a variety of women's faces appearing in pornographic video's that they did not participate in.

And finally, Cate looks at the idea of "social ranking" in our society. Although the idea may have appeared in Black Mirror, it may become a reality.
