Police were on track to lay 32 charges for dealing or trafficking methamphetamine in 2016, fewer than each of the previous three years' totals of 36, 35 and 90.
Mr Wesley made it clear methamphetamine was definitely a problem in the Bay, but he said it wasn't as significant as it was made out to be.
"We've got a P problem - of course we've got a P problem - but it's not growing exponentially, no. It's in line with police figures."
Police replaced its official statistics with a new system in 2014, and cautioned the statistical series over time was not directly comparable with earlier figures.
Prime Minister John Key last week announced a $15 million funding injection to tackle methamphetamine.
This money was split between stemming the supply of the drug and its precursors, as well as expanding and strengthening health treatment programmes to reduce the demand.
Executive director of the Drug Foundation Ross Bell said putting money toward treating drug addiction as a health issue rather than a criminal issue was a positive step.
However, the next day the Government announced a $1 billion prison plan to show it was "deadly serious" on cracking down on methamphetamine and violent crime.
"There's a lot of us, to put it politely, quite upset by the significant contrast shown between the $15m [for methamphetamine] and the $1b [on the prison], and there's a lot of us in the wider health and social sector whose jaws are still dropped - how can this $1b on a prison be true?" Mr Bell said.
"You're not going to ever police away a health issue. Prison is the last place you should send people with mental health and addiction issues."
Mr Bell said 40 per cent of the prison population was incarcerated for drug crime.
"Police are beginning to put more focus on referring people to help rather than processing them through the criminal justice system. We want them to actually formalise some of those things a bit more and make them a nationwide system."
Western Bay Area Commander Inspector Clifford Paxton said police saw "significant challenges" in organised crime, meth and firearms in the Western Bay.
"We're identifying a number of people who are involved in the sale and distribution of meth, and work continues in that area.
"One of the key partners we are working with is health - in particular, iwi health providers - to look at options for creating awareness, empowerment and support."
