The government is being told to come clean about its smoking policies.
The associate Minister of Health says she is committed to looking at a range of options to help smokers to quit but Ministry of Health documents show she's investigating a three year freeze on cigarette taxes - keeping prices stable.
Costello has denied she's specifically asked for a freeze on cigarette taxes, but says it's one of many options being investigated.
Labour Party Health Spokesperson and former Health Minister Ayesha Verrall spoke to Charlotte Cook.
