Talks between the Meat Workers Union and Talley's Affco plants resume again on Monday.

The talks are also set down for May 11 and May 14 and are an advance on previous mediation as they involve recommendations to the Employment Relations Authority.

The meatworkers have been locked out or taking strike action at the company's eight North Island plants for more than two months.

Meanwhile, 33 meatworkers will take their protest to the Talley family's homes at Motueka on Monday.

The workers will represent the 1300 locked-out and striking workers.

The meatworkers will then join workers from a Nelson fishing company for a march in the city.

Last week iwi leaders and Maori farmers said they were prepared to "flex their economic muscle" in a bid to force Affco into good faith negotiations with striking workers.

Maori Party co-leader Pita Sharples said he'd been told Maori farmers across the country planned to withhold stock from Affco meatworks.
