In 1926, the death of William Weir left the University with an estate of £77,500 to build its first hall of residence for male students.

In 1968, the Department of External Affairs funded the James Hutchison Wing as part of the Colombo Plan.

After litigation due to the will of William Weir stating his money was to be used for a male hall of residence, female students were finally allowed to take up residence at Weir House in 1979 as the hall had built its extension through government funding.

The former Japanese ambassador's residence was acquired and converted to Andrea Brander House in 1987, accommodating students who wish to live in an alcohol free area.

In 2006, a new alcohol-free block called Te Whānau was built and has a glass lounge (named Piringa), which is used as a common area.
