Labour has asked the Auditor-General to investigate a government decision to slash tax on heated tobacco products, claiming there are signs of "industry influence". Labour health spokesperson Ayesha Verrall has called for an urgent investigation under the Public Audit Act, and says there are several indications of tobacco industry influence that must be investigated to maintain trust in government. Both Health Minister Shane Reti and Associate Casey Costallo have declined to comment. Ayesha Verrall spoke to Corin Dann.
