An asset rich party

Insolent Prick has done some detective work and discovered that Labour has a huge asset base of over $6 million in property:

Dannevirke Labour $15,700
Greymouth Labour Branch $40,000
Labour Properties Inc $4,800,000
NZ Labour Party Clubrooms Inc $140,000
Picton Branch $11,000
Thames Branch $83,000
Dunedin South $770,000

So tell me again why Labour won’t pay the money back until June next year?
