Experts claim rising unemployment is necessary medicine to get inflation under control.

Stats NZ says unemployment rose to 3.9 percent for the three months to September, up from 3.6 last quarter- and 3.2 a year ago.

Infometrics Principal Economist Brad Olsen says those figures are still a lot better than they've been in recent history.

"Some of the underlying figures suggest that more people coming in from migration, fewer jobs on offer and more people looking for them means there might not be as much additional pressure on prices as we head into next year."
