The Labour Party says it would restore cuts made to frontline biosecurity services if it was elected to government.
Releasing the policy in Te Puke on Wednesday, the party's leader Phil Goff said National had relaxed the vigilance needed against new diseases and pest threats.
Mr Goff said Labour would reinstate jobs axed by National for 54 biosecurity officers working in ports and airports.
He said many industry groups felt the cuts had left New Zealand's borders more vulnerable.
Labour said it would also convene a summit of all stakeholders in the bee industry to develop a plan for protection of the bee population.
