Prime Minister John Key has been dumped from a climate change debate in Copenhagen, with Australian Prime Minister Kevin Rudd set to take his place.
The debate was due to be aired on the BBC tomorrow morning NZ time and includes Mexican President Felipe Calderon and South African President Jacob Zuma.
Mr Key's delegation was told of the switch overnight.
Trade Minister Tim Groser said it was an unfortunate development, but little could be done about it.
Is John Key achieving anything at the Copenhagen climate summit?
