Labour Party President Nigel Haworth says the National Party is still grieving about losing power after the 2017 election.
"Their sense of entitlement is on full display," he told the Labour conference in Dunedin this morning.
"Cornered creatures attack and they attack fiercely - so it will be with National.
"They will do what they will to regain power.
"National is still grieving about the loss that they faced and that they still manifest a view that somehow they were cheated, that somehow something happened that wasn't fair, wasn't reasonable and they are clearly fighting very hard to come back to power."
