One of the ministers nailing his new job, in my humble opinion, is Commerce Minister Kris Faafoi.
He got onto the Takata airbag recall, he's talking butt kicking for wheel clampers, and now we hear the news he's on to Visa and Mastercard over their fees.
If they hike their fees he warns, they'll face Australian and UK-style legislation to cap them. Threatening to regulate is always a strong stance by governments - and effective in serving an upper cut to business, while reassuring the consumer that someone's in their corner.
Faafoi wants to see the cost of payments to be "fairly" shared between New Zealand business and consumers, which he doesn't think is currently happening.
So, he says, if he sees those fees move north, then regulating them is an option on the table. Effectively what he's doing is putting credit card companies on notice.
