Justin Timberlake's posted pictures of sweeping beach scenes on Auckland's west coast to his six million followers on Instagram.

The shots appear to have been taken at Whatipu, with his wife Jessica Biel.

The star's in Auckland for three concerts - tonight's the last one.

He's hash-tagged one shot, "on top of the world" .... including the quote, "life moves pretty fast, if you don't stop and look around once in a while you could miss it".
