Backblock tells rural New Zealand delivery addresses from urban ones at checkout and shows the matching rate you set. Rural buyers see your rural rate, urban buyers your standard rate; the other is hidden. It reads a numbered RD route off the address line, otherwise checks the postcode against 711 NZ rural delivery postcodes. You enter the prices. Backblock supplies, calculates and prefills nothing. Carts over 25 kg do what you choose: blocked, or a flat rate you set. New Zealand only.

• Rural and urban New Zealand delivery addresses told apart at checkout
• You set both rates. Backblock prefills no prices and supplies no carrier pricing
• Reads numbered RD routes off the address line, then rural delivery postcodes
• Creates its own delivery profile. Your existing shipping profiles stay untouched
• You control oversize carts: block them over 25 kg, or charge a flat rate you set
