Spa Sommaai is a Thai massage day spa inside the Heritage Auckland Hotel on Wyndham Street in the CBD, and the website says it is one of the few true hotel spas in the city. It is known for its couples massage: two therapists work side by side in a private room. Valet parking is available. Treatments are 60 or 90 minute Signature or Sensations massages. As at 2026, a 60 minute treatment is $99, a 90 minute one is $149, a couples 60 minute treatment is $198 and a couples 90 minute treatment is $298. The menu also includes hot oil rituals, facials and body treatments, and gift vouchers can be sent digitally. The spa says it has won best spa awards four years in a row.
Customers mention couples massage most, along with firm pressure, a good choice of oils and skilled therapists. One visitor who had flown in from the US after a 29 hour journey had a 90 minute deep tissue massage and went back five days later. Another enjoyed a spa day with a massage and facial, and one praised the green tea welcome and the foot bath. Our pick in the CBD for a couples massage or a slow spa afternoon.
