Peacekeeping in Ukraine will be an extensive operation, according to one expert.

UK Prime Minister Sir Keir Starmer has rallied together leaders from Europe, Canada, Australia and New Zealand for a virtual meeting that he's dubbed the 'coalition of the willing'.

Discussions focused on supporting Ukraine to achieve lasting peace.

Kiwi K.A.R.E founder Tenby Powell says a peacekeeping force will need to cover a large frontline.

"The question that I would ask the Minister of Defence is - do we have the numbers to be able to make a sustained effort. So we're making an impactful and meaningful contribution."
