Tony Abbott's approval rating has hit its lowest point in five months, the latest Newspoll shows.

The survey, conducted for News Corp at the weekend, reports a drop in the prime minister's satisfaction rating for a fourth consecutive month, giving him 33 percent.

Opposition Leader Bill Shorten remains the preferred prime minister, with his level unchanged at 39 percent.

The government and opposition are tied for the primary vote on 37 percent each after the coalition picked up a point and the opposition lost two.

Labor maintained in front on a two-party-preferred basis, leading 54 to 46 percent.

The Greens moved up two points to 13 percent, while minor parties, independents and others dropped a point to also sit on 13 percent.
