The week before the election saw the Velas donate $200,000 to Labour First, or more formally $100,000 each to the constituent Labour and NZ First parties.
The donation was made on 31 October. The EPMU also donated $60,000 that day. Labour revealed the EPMU donation on 5 November, but held off revealing the Vela donations until after the election. They were able to do this legally as you have two weeks to declare large donations.
This reinforces to me the need for a Commission of Inquiry into the matters alleged in the Meurant papers. I hope the Greens keep pushing for it, and that the new Government agrees.
