Forder Lectureship 
In 1986 the Council of the London Mathematical Society, in consultation with Officers of the New Zealand Mathematical Society, instituted a Lectureship to New Zealand. The Lectureship is named after the late Professor H. G. Forder, formerly of the University of Auckland, and a benefactor of the London Mathematical Society.
The Forder Lectureship normally occurs every two years (in odd-numbered years) when a mathematician from the UK, who is a member of the London Mathematical Society and normally resident in the United Kingdom, is invited by both Societies to give lectures at most universities in New Zealand over a period of four weeks.
Forder lecturers are chosen for their eminent contribution as a research mathematician and who can also speak effectively at a more popular level.

Aitken Lectureship
In 2009, the London Mathematical Society and New Zealand Mathematical Society agreed to set up a new lectureship which is named after Professor A. Aitken, one of New Zealand’s great mathematicians, for a period of ten years.
The Aitken Lectureship occurred every two years (in even-numbered years) when a mathematician from New Zealand was invited by both Societies to give lectures at different universities around the UK over a period of several weeks.
