Kaikoura is a beautiful and amazing part of New Zealand. It has an awesome laid back vibe. As a town they are big on conservation and eco-tourism so if that's your thing you will love it here! You can whale watch, swim with dolphins and seals and watch Albatross fly all in their natural environment. No SeaWorld cruelty! Some decent hikes/ tramps in the area and the local restaurants do excellent Seafood, as you'd expect!
Insider Tip:Check your change at the Strawberry Tree - They have a history of burning the tourists!
