The National Welfare & Recovery Group will continue to work with regional and district authorities as required to set up further structures as need is identified.

A phone survey has been established, based on Fed Farmers database, to ascertain scope and scale of farmers' needs.

Six strategic areas of focus have been identified:

  • Communications
  • Labour coordination
  • Donations and distribution
  • Technical support
  • Welfare matters
Infrastructure:

State Highway status continues to improve however the Manawatu Gorge SH3 will be closed for at least a week. Within Manawatu-Wanganui extensive road and bridge damage has been assessed and a work programme put in place.

All main-trunk rail lines are open, with a diversion between Marton and Whareroa to allow dairy deliveries to Hawera. The Marton-New Plymouth line will not open until next Thursday 26th due damage to the Whangaehu Bridge.

Gas supplies to all Hawke's Bay customers were restored late Friday 20 February. Customers without electricity in rural areas such as Ngamatapouri and Mangamahu have been reduced to less than 200.

Several water supplies need boiling due contamination, but main supplies have been restored in Bulls, Hunterville, Fielding and Mangaweka. Water supply for Waitotara, Hunterville and Ratana are via tanker until bore supplies clear and tanks are cleaned.
