British Foreign Secretary William Hague is set to make his second visit to New Zealand in two years.
Mr McCully said the talks in Auckland on Tuesday, the second day of Mr Hague's two-day itinerary, would be a chance to address critical foreign policy issues.
Likely to be on the agenda would be Iran and Syria, the Middle East peace process, and developments in Afghanistan, Fiji and Myanmar.
In Auckland, Mr Hague will meet New Zealand business people, young Pacific leaders, academics and representatives of non-governmental organisations.
In Christchurch, he will lay a wreath at the HMNZS Pegasus naval base in honour of New Zealand service personnel.
