Organisers promise a final international artist will announced on Monday November 2.
Several local acts were added to the bill, including sludge-metallers Beastwars, indie punks Die! Die! Die!, and Lyttelton folk songstress Aldous Harding, bringing the Kiwi contingent to around two-thirds of the line up.
Two previously announced acts - The Phoenix Foundation and P-Money - are no longer on the bill.
Despite the forced move, the organisers maintain the new location will offer a full festival experience, with markets and street food stalls operating from lunchtime until late on both days. It will be a multi-stage festival, with stages located inside and outside Vector Arena.
Echo Festival remains an all-ages event, with two-day and single day ticket options available, as well as discount tickets for children (5-11) and youth (12-16).
Ticket details are available at www.echofestival.co.nz.
McLaren Valley Music and Arts Festival tickets can be exchanged for Echo Festival tickets, or full refunds on festival and camping tickets are available from point of purchase. All refunds must be processed by Wednesday November 18
