New Zealand First MP Shane Jones has urged farmers to remember who has constantly batted for them within the coalition Government over the last three years.

Mr Jones says the current polls reflect the 'major randomness' there is in politics, and hopes farmers will vote strategically in their favour.

"The farmers need to identify who their true friends have been over the last three years as a part of the coalition Government."

Meanwhile, Mr Jones maintains the Provincial Growth Fund, while facing its challenges, will still deliver on 'productivity, offer jobs and change fortunes of the provincial economies'.

"It does take time sadly and often the local Government applicants haven't got all their ducks in a row," Mr Jones says.

"It's flowing, the projects are gathering momentum."

By election day, Mr Jones expects to have spent all of the fund's $3 billion.
