She is looking forward to getting on stage in Rotorua and is promising a "high energy" '70s style performance.
"Most of it is very up tempo. I won't be sitting down," the nearly 70-year-old said.
Graham and the New Seekers will perform in Rotorua as part of Smash Hits 70s: The Greatest Hits of the New Seekers and Paper Lace on May 2.
The concert will be held at the Civic Theatre, with tickets available from Ticketmaster.
The tour will start in Hamilton on April 28 before travelling to Auckland, Tauranga, Rotorua, Hastings, New Plymouth, Palmerston North, Wellington, Greymouth, Christchurch, Dunedin and Invercargill.
Graham says the tour is a real nostalgia event and is expecting fans to come to the concert and reminisce about the '70s.
"It's going to be nostalgia made up of the hits from the '70s.
"The audience will know what to expect and they're not going to be disappointed."
Graham has had a music career which has lasted more than 50 years. Her message for anyone wanting to get into the music industry is to do it because you love it, not because you want to be famous.
