"You make life-long friends through the exchanges as well as visit some lovely places."
Mary Dettling says since she got involved with the Stratfords of the World committee in 2010 she has made many new friends through the exchanges organised every two years.
"There are six Stratfords involved in total and every two years residents from each of the Stratfords meet up in one of the towns for a reunion."
As well as New Zealand, the other Stratfords are in England (Stratford-Upon-Avon), Australia, Ontario, Connecticut and Prince Edward Island.
Mary says the main objective of what is known as the Sister Cities programme is the promotion of friendship and cultural exchange between the participating countries.
