"It's been seen around the world and any good performances in short-form cricket are picked up by people in India or the likes of the Caribbean league or the other leagues around the world," he said. "It certainly hasn't done him any harm."
Asked if his performance would put him in the top bracket of IPL earners, Mills said it was hard to know.
The Mumbai Indians paid US$1 million ($1.2 million) for Australian all-rounder Glenn Maxwell last year, who had at that stage played only eight one-dayers and nine T20s for his country.
Anderson and other Kiwi players interested in going under the hammer at the auction were yet to sign a pre-auction agreement that goes through New Zealand Cricket to the BCCI (Board of Control for Cricket in India), but Mills said this was likely to happen over the next week.
He said as India toured New Zealand over the next month players such as Anderson had good opportunities to show off their talents to prospective franchises.
