The balance of the required $220 million will come from bank debt.
Company chairman Mr Norgate was headed to Dubai and chief executive Mr Miles to Australia.
Mr Norgate expected to have the financing completed by next week.
Speaking after yesterday's shareholder meeting in Dunedin, Mr Norgate said access to debt had become tighter in recent weeks, but equity markets had not changed in the same way, so the decision had been taken to change the funding make-up.
Originally, PGG Wrightson (PGG-W) was going to fund the purchase through $75 million of equity and $145 million in debt but the international credit crunch prompted a rethink.
The impact of the funding on SFF was graphically illustrated by chief executive Keith Cooper at the meeting.
SFF has $50 million in bonds to be refinanced in April next year and $75 million in December 2010, while debt would be completely wiped from next year and the company could have close to $150 million in cash by 2015.
Mr Norgate said suppliers would want to see measurable change within three months.
The issue was about competing land use, and success or failure of the partnership would be measured by improved stock prices stopping the flow of sheep and beef farmers shifting to dairying.
"For the first time in several years, sheep farmers will have a reason not to go to dairying."
Ultimately, he hoped to see a return to intensively farmed land being used to finish lambs.
Mr Cooper said it would take a year before the new model could be accurately judged, but he said suppliers would measure success or failure on the size of their annual rebate payments.
It would also be measured on the level of farmer support for the new model and whether it succeeded in settling a new, higher benchmark price for prime stock.
Mr Cooper accepted some shareholders did not like it, but he hoped it would not affect a normal business relationship.
Mr Norgate said the change was to help all shareholders, including those who voted against it.
"I hope they are going to give it a chance to fly."
Mr Norgate said SFF was getting capital, procurement capability, business governance and on-farm management expertise, marketing knowledge and industry consolidation.
PGG-W would benefit from clients who were financially more viable because of higher returns.
