Christchurch Mayor Bob Parker is to visit South Korea and Israel for eight days.
He will leave this Thursday, returning to Christchurch on Friday May 11.
While in South Korea, Mr Parker will travel to Christchurch's sister city Songpa-Gu and also speak at a business breakfast in Seoul hosted by the Kiwi Chamber of Commerce.
A highlight is a visit to the Korean Antarctic Programme.
After Korea, he will travel to Israel for the International Mayors' Conference, to be attended by 73 mayors from around the world. The invitation to Mr Parker follows a visit to Christchurch in April last year by Israel's Speaker of the Knesset Reuven Rivlin.
