The Dunedin City Council is to join a "coalition of the willing" by adding its name to an alliance of South Island councils.
Councillors at yesterday's full council meeting voted unanimously, and without debate, to join the South Island Strategic Alliance (SISA).
The grouping of up to 27 South Island councils had been discussed since last year, and in recent weeks endorsed by the Otago Regional Council, and Central Otago and Clutha District Councils.
A report to yesterday's council meeting in Dunedin said the "coalition of the willing" would help promote a "South Island voice", including when talking to the Government in Wellington.
Dunedin Mayor Dave Cull told Radio New Zealand the alliance helps give the South Island a collective voice which isn't fragmented when dealing with central government.
