National Party members have been warned not to allow opinion polls to lull them into complacency over next year's election.
Prime Minister John Key and party president Peter Goodfellow delivered the message at National's annual conference in Christchurch.
"There's no room for complacency, no room for arrogance and no room for mediocrity," Mr Key said in his speech to delegates today.
He has previously warned that although the polls show National with a strong lead, opposition parties together are putting up "big numbers".
"Labour, the Greens and NZ First could potentially tip over a National-led Government - and we know that with every election it gets harder to win."
Mr Goodfellow told the conference yesterday National had an opportunity, unprecedented under MMP, to win a fourth term next year.
"However, our greatest risk is that we take for granted the enormous support New Zealanders have shown the National-led Government over the last eight years," he said.
"We have simply worked too hard and too long to be defeated by complacency now."
