Elton John's date changes in New Zealand are due to the star attending the Oscars.

The date of his Dunedin show - February the 4th stands.

But the Napier Mission Estate Winery and both Auckland concerts have been pushed back a week.

As well, a third show has been added in Auckland.

Promoter Michael Chugg told Mike Hosking the Oscars were brought forward to February 9 and they had no choice.

"Especially given the fact that Rocketman the movie is coming out at the end of this month and all predications are that it is probably going to be one of the biggest music movies ever."

Chugg says they have known for a while but decided to hold off on releasing the news after the events in Christchurch.

Tickets for the third Mount Smart Stadium show go on sale later this month.
