Should the government implement a wealth tax on the richest citizens?

A Wealth Tax is distinct from income tax or capital gains tax; it is an annual levy on a person's total net assets (houses, shares, cash) minus their debts. Proponents, typically on the left (Greens, Te Pāti Māori), argue that New Zealand is a tax haven for the super-rich and that this revenue is needed to fund dental care or poverty reduction. Opponents (National, ACT) argue it penalizes success, is difficult to implement (how do you value a farm every year?), and causes "capital flight," where wealthy individuals move their money offshore.
