Pinehaven is the perfect place to unwind no matter you're a solo traveller or small family. Only 2 hr drive from Auckland, it's close to Waihi Beach and a short distance from the supermarket. However you would not want to leave the cottage as the beautiful views and atmosphere is more rarely found. The spa is definitely a bonus, especially when you enjoy it under the night sky. My favorite is still the river though, a perfect background music for meditation or yoga practice.
Special thanks to Jill and Glen. They are the most friendly hosts you can ever see. Give you lots of privacy and local guidance when needed.
Will definitely come back.
