KEY POINTS:
National Party political strategist Crosby/Textor is drumming up business after last week's election by offering insights into the new Government and its personalities.
The Australian company also plans to expand in New Zealand, joint managing director Mark Textor said in a leaked email to business contacts this week.
He is also offering insights into changes in New Zealanders' attitudes and what lies behind them.
National leader and Prime Minister-in-waiting John Key has previously refused to confirm that the consultants worked for National.
But through a spokesman last night, Mr Key said he had no concerns about the email.
"It is not surprising that they and other consultants used by National seek to associate themselves with our electoral success."
National had had an association with the firm since the 1990s, and in this election it had helped the party run a positive campaign.
Crosby/Textor has advised the Liberals in Australia, the Conservatives in Britain and was behind Boris Johnson's successful campaign for the London mayoralty.
Mr Textor's letter said his company had given National " high-level counsel on the execution of the election campaign strategy".
His email said that his company had helped over many years to measure and shape New Zealand voters, customers and investors' attitudes through polling and communications campaigns.
"As such, we are uniquely placed to provide you with insights and advice as to what this historic change in political dynamics really means for companies and businesses seeking to deal with Government (including the personalities involved) and the New Zealand community generally over the coming term."
Mr Textor outlined National's "clear plan of action" including tax cuts to encourage growth, cutting Government waste, improving productivity, improving infrastructure and a focus on education standards.
Mr Textor said the election of Mr Key would have a significant effect on Government policy, decision-making and on business and consumers.
"How Government policy will be made and implemented will change," Mr Textor said, although he did not give any details.
He could not be contacted last night.
